Find the missing angles in the parallelogram

Explanation:

On the first pass, you know ...

g = 80° . . . vertical angles I = 110° . . . vertical anglesm = 20° . . . alternate interior angles (WX║ZY)

Then on the second pass, you can figure ...

f = h = 180° -80° = 100° . . . linear anglesj = k = 180° -110° = 70° . . . linear anglesb = n = 180° -110° -m = 50° . . . sum of angles of a triangle

And the remaining angles can be determined using external angle and sum-of-angle relationships.

a = o = h -70° = 30°c = 80° -b  = 30°d = 360° -80° -20° -I = 150°L = c - m = 10° . . . c and L+m are alternate interior anglese = L +70°  or  110° - o = 80°

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
