∴ x = 7 + 2 (Transposing – 2 to RHS)
∴ x = 9

Question 2.
y + 3 = 10
Solution:
y + 3 = 10
∴ y = 10 – 3 (Transposing 3 to RHS)
∴ y = 7

Question 3.
6 = z + 2
Solution:
6 = z + 2
∴ z + 2 = 6 (Interchanging both the sides)
∴ z = 6 – 2 (Transposing 2 to RHS)
∴ z = 4.

Question 4.
\(\frac {3}{7}\) + x = \(\frac {17}{7}\)
Solution:
\(\frac {3}{7}\) + x = \(\frac {17}{7}\)
∴ x = \(\frac{17}{7}-\frac{3}{7}\) (Transposing \(\frac {3}{7}\) to RHS)
∴ x = \(\frac{17-3}{7}\)
∴ x = \(\frac {14}{7}\)
∴ x = 2

Question 5.
6x = 12
Solution:
6x = 12
∴ \(\frac{6 x}{6}=\frac{12}{6}\) (Dividing both the sides by 6)
∴ x = 2

Question 6.
\(\frac{t}{5}\) = 10
Solution:
\(\frac{t}{5}\) = 10
∴ \(\frac{t}{5}\) × 5 = 10 × 5 (Multiplying both the sides by 5)
∴ t = 50

∴ \(\frac{14 y}{14}=\frac{21}{14}\) (Dividing both the sides by 14)
∴ y = \(\frac{7 \times 3}{7 \times 2}\)
∴ y = \(\frac {3}{2}\)

Question 11.
17 + 16p = 9
Solution:
17 + 16p = 9
∴ 6p = 9 – 17 (Transposing 17 to RHS)
∴ 6p = -8
∴ \(\frac{6 p}{6}=\frac{-8}{6}\) (Dividing both the sides by 6)
∴ p = \(\frac{-4 \times 2}{3 \times 2}\)
∴ p = –\(\frac {4}{3}\)

Question 12.
\(\frac{x}{3}+1=\frac{7}{15}\)
Solution:
\(\frac{x}{3}+1=\frac{7}{15}\)
∴ \(\frac{x}{3}=\frac{7}{15}-1\) (Transposing 1 to RHS)
∴ \(\frac{7-15}{15}\) (LCM = 15)
∴ \(\frac{x}{3}=\frac{-8}{15}\)
∴ \(\frac{x}{3} \times 3=\frac{-8}{15} \times 3\) (Multiplying both the sides by 3)

= 9 : 5

Question (iiii)
91 : 104
Solution:
To express this ratio in the simplest form, we shall have to divide both terms by their H.C.F.

So H.C.F. of 91 and 104 = 13
∴ 91 : 104 = (91 ÷ 13) : (104 ÷ 13)
= 7 : 8

Question (iv)
60 : 72
Solution:
To express this ratio in the simplest form, we shall have to divide both terms by their H.C.F.

So H.C.F. of 60 and 72 = 12

Also, unlike us, it lacks a well-developed nervous system although it responds to many external stimuli. The, tree breathes through its leaves.

How does the environment affect the growth of the tree ? If there is a lack of water, the roots go down deeper and spread out far and wide, backward and forward, in search of food material. If there are too many trees in one place, they grow higher and higher to reach the sunshine. If there is a strong wind all the time, the tree takes firmer hold of the ground with its roots.

The tree is a strong fighter. It may bend before the wind but it does not always break. It protects itself very well against snow, frost and hail. It can defeat most of its enemies.

Answer:
\(\left\{\frac{7}{5} \times\left(\frac{-3}{12}\right)\right\}+\left\{\frac{7}{5} \times \frac{5}{12}\right\}\)
= \(=\frac{7}{5} \times\left[\frac{-3}{12}+\frac{5}{12}\right]\)
= \(\frac{7}{5} \times\left[\frac{-3+5}{12}\right]\)
= \(\frac{7}{5} \times \frac{2}{12}\)

PSEB Solutions for Class 10 Maths Chapter 8 Introduction to Trigonometry Ex 8.3

Question 1.
Evaluate:
(i) \(\frac{\sin 18^{\circ}}{\cos 72^{\circ}}\)
(ii) \(\frac{\tan 26^{\circ}}{\cot 64^{\circ}}\)
(iii) cos 48° – sin 42°
(iv) cosec 31° – sec 59°.
Solution.
(i) \(\frac{\sin 18^{\circ}}{\cos 72^{\circ}}\)
= \(\frac{\sin 18^{\circ}}{\cos \left(90^{\circ}-18^{\circ}\right)}\)
= \(\frac{\sin 18^{\circ}}{\sin 18^{\circ}}\) = 1
[∵ cos (90° – θ) = sin θ]

(ii) \(\frac{\tan 26^{\circ}}{\cos 64^{\circ}}=\frac{\tan 26^{\circ}}{\cot \left(90^{\circ}-26^{\circ}\right)}\)
= \(\frac{\tan 26^{\circ}}{\tan 26^{\circ}}\) = 1
[∵ cot (90°- θ) = tan θ]

(iii) cos 48° – sin 42°
= cos (90° – 42°) – sin 42°
[∵ cos (90° – 0) = sin O]
= sin 42° – sin 42° = 0.

(iv) cosec 31° – sec 59°
=cosec 31° – sec (90° – 31°)
= cosec 31° – cosec 31°
[∵ sec (90° – θ) = cosec θ].

Question 2.
Show that:
(i) tan 4 tan 230 tan 42° tan 67° = 1
(ii) cos 38° cos 52° – sin 38° sin 52° = 0
Solution:
(i) L.H.S.
= tan 48° tan 23° tan 42° tan 67°
= tan 48° × tan 23° × tan (90° – 48°) × tan (90° – 23°)
= tan48° × tan 23° × cot48° × cot 23°
= tan 48C × tan 23° × \(\frac{1}{\tan 48^{\circ}}\) × \(\frac{1}{\tan 23^{\circ}}\) = 1
∴ L.H.S. = R.H.S.

(ii) L.H.S.= cos 38° cos 52° – sin 38° sin 52°
= cos 38° × cos (90 – 38°) – sin 38° × sin (90° – 38°)
= cos 38° × sin 38° – sin 38° × cos 38
= 0.
∴ L.H.S. = RH.S.

Question 3.
If tan 2A = cot (A – 18°) where 2A is an acute angle, find the value of A.
Solution:
Given: tan 2A = cot (A – 18°)
⇒ cot (90° – 2A) = cot (A – 18°)
[cot (90° – θ) = tan θ]
⇒ 90°- 2A = A – 18°
⇒ 3A = 108°
⇒A = 36°.

Question 4.
If tan A = cot B, prove that A + B = 90°.
Solution:
Given that: tan A = cot B
⇒ tan A = tan(90° – B)
[∵ tan (90° – θ) = cot θ]
⇒ A = 90° – B.
⇒ A + B = 90°..

Question 5.
If sec 4A = cosec (A – 20°), where 4A is an acute angle, find the value of A.
Solution:
Given that: sec 4A = cosec (A – 20°)
⇒ cosec (90° – 4A) = cosec (A — 20°)
[∵ cosec (90° – θ) = sec θ]
⇒ 90° – 4A = A – 20°
⇒ 5A = 110°
⇒ A = 22°.

Question 6.
If A, B and C interior angles of a triangle ABC, then show that: \(\sin \left(\frac{B+C}{2}\right)=\cos \left(\frac{A}{2}\right)\)
Solution:
Since, A, B and C are interior angles of a triangle
∴ A + B + C = 180°
[Sum of three angles of a triangle is 180°]
⇒ B + C = 180° – A
⇒ \(\frac{\mathrm{B}+\mathrm{C}}{2}=\frac{180^{\circ}-\mathrm{A}}{2}\)
⇒ \(\frac{\mathrm{B}+\mathrm{C}}{2}=\left(90^{\circ}-\frac{\mathrm{A}}{2}\right)\)
Taking sin on both sides, we get
⇒ \(\sin \left(\frac{\mathrm{B}+\mathrm{C}}{2}\right)=\sin \left(90^{\circ}-\frac{\mathrm{A}}{2}\right)\)
[∵ sin (90° – θ) = cos θ].

Question 7.
Express sin 67° + cos 75° in terms of Trigonometric ratios of angles between 0° and 45°.
Solution:
Given that: sin 67° + cos 75°
= sin (90° – 23°) + cos (90° – 15°)
= cos 23° + sin 15°
[∵ sin(90° – θ) = cos θ and cos (90° – θ) = sin θ].
