Question

Solve for x

(I’ve tried everything I can think of, but I still haven’t been able to solve this. Please help!)

Answer 1

x = 6

∠2 = 75

Explanation:

In the given triangle two sides are equal and so it is an isosceles triangle. So, the angles opposite to equal sides are equal

11x + 9 + 11x + 9 + 30 = 180 {Angle sum property of triangle}

11x + 11x + 9 +9 +30 = 180

22x + 48 = 180

22x = 180 - 48

22x = 132

x = 132/22

x = 6

∠2 = 11*6 + 9 = 66 +9 = 75
