find the value of x
I tried writing out the problem and I got 90 can someone tell me what I did wrong and

Answer 1

This is an isosceles triangle, which means that the two other angles are the same degree number.
All three angles will equal 180* after adding them together.
180*- 30*= 150*
150* / 2 = 75*

Therefore, x=75*
