Hey there,

Both [tex]x[/tex] = 85 and [tex]y = [/tex]are 80°.

1.) First off, the reason why there would be 80° would be because by looking at this angel, this angel is a obtuse angel. And also, it is also close to being a (right angel). And a right angel is 90°. So this is a clue that it would be around there.

2.) The area of this figure would be 300°.So in order to find the other angel's, we would have plug in both x =85 and also y=80.

Hope this helps.

see attachment: you have 2 triangles

red one has 2 given angles 40 and 30

40+30 = 70 so the 3rd angle needs to equal 180-70 = 110

 part of that angle is 30 so x = 110-30 = 80


the yellow triangle has given angles of 35 and 30

35+30=65

 3rd angle needs to equal 180-65 = 115

part of that angle is given as 30 so y = 115-30 = 85



 that's how you actually find the answer.


it has nothing to do with area or that one angle is close to 90 or anything like that.
