Answer:

answer is 10

Step-by-step explanation:

(4x+12)+(4x+12)+(5x+26)=180[sum of isosceles triangles]

8x+34+5x+26=180

X=10

(4x+12) + (4x+12) + (5x+26) = 180
13x + 50 = 180
13x = 130
X = 10

Now that you found the value of x, plug that number into the equations they gave you for the angles...
angles G and H = 4(10) + 12 = 52
angle I = 5(10) + 26 = 76
