angles with common sides and a common vertex

silvernight269:

Yes exactly.

silvernight269:

So from what you can see in the picture show, remember they're also asking for what number represents an adjacent angle, what can we see meaning which numbers do you think could be the adjacent angle?

ok so that you got 2 angles. you need to find the missing angle: a. If you ignore the 70 and a you have a right angle. a right angle is a 90 degree angle. all you need to do is minus 70 from 90 and u get the missing angle

70 - 90 or 90 - 70

90-70

Thats a vertical angle I believe so like e is 129 and 129 -90 equals f and a lime is 180 so if one side is 90 then d is 90 because 90+90=180

BeautyQueen:

I think thats how you do the problem
