Question

find the unknown angles in the following figure..
With explanation ...​

Answer 1

Step-by-step explanation:

Since AB=BC

So, angle ACB = angle CAB( angles opposite to equal sides are equal)

Let angle ACB and CAB be b°

So, b+b+10+90=180°

Or, 2b+100=180

Or, 2b=80

Or, b=40°

So, angleCAB=b+10=40+10=50°

angle ACB = b=40°
