Triangles helpp

Answer 1

How do i find the angles?

Answer 2

Well, the triangle is isosceles and the base is GH. Therefore, we know that the measure of angle H= measure of angle G.
The degrees of a triangle must also add up to 180 degrees.

So:
angle H + angle G + angle F = 180
(5x+11)+(5x+11)+(3x+41)=180
13x+63=180
13x=117
x=9

Angle H and angle G are (5x+11). We know that x=9. Therefore, angle H and G must be 56 degrees. Can you find the measure of angle F?
