Answer:

Option C. x = 16

Step-by-step explanation:

In the given right angle triangle Base or adjacent side = 8 units

Height or opposite side of the angle = x units and hypotenuse = x units

We have to tell the value of x.

Since we know in a right angle triangle cosx = Base / hypotenuse

cos 60 = 8/x

1/2 = 8/x

x = 8 × 2

x = 16  

Therefore Option C. 16 units is the answer.
