D+G=180 ... (2)

Given E=78,

Solve for D from (1), and hence G from (2).

**MathMate**, Sunday, December 5, 2010 at 5:16pmLet's do a check:

From (1)

D+E=90 => 12+78=90 OK

From (2)

D+G=180 => 12+118=130 ≠ 180 ??

Let's solve for G from (2):

D+G=180

12+G=180

12-12+G = 180-12

G=168

Post if it's still not clear.
