Question

Find the degree of each angle of the triangle

Answer 1

51,51,78

Explanation:

First of all equate the two angles since it is isoceles.

3x+9= 4x-5 , therefore x= 14

sub that in and find the rest of the angles.

angle G---> 4*14 -5 = 51

angle I--->3*14+9= 51

last angle 180 - 2*51 = 78
