PLEASE PLEASE HELP!! I'm a bit behind with math, and you'd be doing me a huge huge favor! thank you so much in advance. (:

Answer 1

All triangles equal 180 the exterior line and the missing corner are supplementary meaning that that 1=168

Answer 2

It is 168. Because the right angle is 90 degrees. The other one is 78. 78+98 = 168. So 180 degrees - 12 degrees is 168.
