Question

Find the measure of the indicated angle

Answer 1

? = 27

Explanation:

Keep in mind that all angles in a triangle equal 180

Add up all the known angles in triangle 1

90 + 33 = 123

and subtract it by 180 to find the third angle

180 - 123 = 57

then subtract 57 by 90 to find the other side of 90 degree angle the to triangles share

90 - 57 = 33

next add the angle we just found by 120

120 + 33 = 153

finally subtract 180 by 153

180 - 153 = 27

Answer 2

27

Explanation:

180-(90+33)=57

90-57=33

180-(120+33)=27
