Question

The semi circle and the isoceles traingle have the same base AB and the same area. Find the angle x.

Answer 1

Step-by-step explanation:

Where is angle x ?

If it helps, area of ∆Abc =area of circle

= 1/2 ×b × h = πr²/2

= bh= πr²,

now base is AB and AB is diameter, so base= 2r

= 2hr = πr²

= h= πr/2
