Question

GHK is am isosceles triangle, GH=GK and angle G =30degree. Fing angle H​

Answer 1

Answer:

solution, Here;

Triangle GHK is a isosceles triangle.

GH=GK

Angle G = 30

Let angle H be x

Therefore, angle K= x. ..... (Base angles of an isosceles triangle are equal )

We know that,

Angle (G +H + K) = 180degree. . (sum of triangle is 180 degree )

30 degree + x + x = 180 degree

30 degree + 2x = 180 degree

2x =( 180 - 30) degree

x = 150÷2

therfore, x = 75 degree

• Thus, angle H is 75 degree
