Answer:
The correct answer is option a. 21.2
Step-by-step explanation:
It is given that, a right angled triangle ABC right angled at C
<u>To find the value of b</u>
From the figure we get,
m<B = 62º and c=24
Sin B = Opposite side/Hypotenuse = AC/AB = b/c
b = c * Sin B = 24 * Sin 62
= 24 * 0.8829 = 21.19 ≈ 21.2
Therefore the correct answer is option a. 21.2
