Answer:

G = 109

Explanation:

The exterior angle is equal to the sum of the opposite interior angles.

12x-10 = 73+ 7x-3

Combine like terms.

12x-10 = 70+ 7x

Subtract 7x from each side.

12x-10-7x= 70+7x-7x

5x-10 = 70

Add 10 to each side.

5x-10+10 = 70+10

5x= 80

Divide each side by 5.

5x/5 = 80/5

x = 16

Now we can find angle G.

7x-3

7*16-3

112-3

109

G = 109
