I know the four angles add to 360 deg. So the two unknowns are 50 deg together. 20 and 30 deg angles would give a ratio of 2:3, but what is the equation I would use to figure this using the ratio and the 50 deg?

**Henry**, Friday, April 22, 2011 at 10:25pmLarger angle = X Deg.

Smaller angle = 2X/3 Deg.

X + 2X/3 = 360 - 310 = 50,

Multiply both sides by 3:

3X + 2x = 150,

5X = 150,

X = 30 deg.

2X/3 = 2/3(30) = 20 Deg.
