Question

In the given figure triangle ABC, AC=100, CB= 50 , then find the value of x?

Answer 1

Step-by-step explanation:

Given that

∆ABC is a right angled triangle

angle B = 90°

BC = 50 units

Hypotenuse (H) = AC

AC = 100 units

We know that

Cos A = Adjacent side to angle A / Hypotenuse

→Cos x = BC / AC

→Cos x = 50/100

→Cos x = 1/2

→Cos x = Cos 60°

.°. x = 60°

Hence, the value of “x” is 60°
