Question 12552
If the angles are supplementary, that means the sum of the two angles should be 180.
<P>

7x + 10 + 3x = 180 Combine Link Terms
10x + 10 = 180 Subtract 10 on both sides
10x = 170 Divide by 10 on both sides
x = 17.
<P>

if x = 17 then
G = 7(17) + 10 = 119 + 10 = 129
H = 3(17) = 51

<BR>
129 + 51 = 180
