Answer 2

Step-by-step explanation:

Given :-

100 units and 50 units

To find:-

Find the value of x ?

Solution :-

Given that

∆ABC is a right angled triangle

angle B = 90°

BC = 50 units

Hypotenuse = 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°

Therefore, x = 60°

Answer:-

The value of x for the given problem is 60°

Used formulae:-

• Cos A = Adjacent side to angle A / Hypotenuse

• Cos 60° = 1/2
