Answer:
So the side with the red square is 90 degrees. Anytime you see that that's what it will be. The inside of the triangle should equal 180 so 90 + 60 is 150. 180-150 = 30
Two side lengths are 90 and 30.
Step-by-step explanation:
If the x and y are pythagorean theorem then a2+b2=c2
If not then y= 120
and x= 150
the outside should equal 360
