Question

I need help on this question

Answer 1

It should add up to 180˚.

180˚ - 30˚ = 50˚

So x = 50˚

Hope this Helps!!

Answer 2

triangle has 2 equal sides so it's isosceles triangle

<A = <C

sum of interior angles in a triangle = 180

180 - 30 = 150

<A = <C = 150/2 = 75

x = 180 - 75

x = 105

answer

x = 105°
