Question

What are the values of x and y in the diagram? A. x = 77° y = 93° B. x = 87° y = 83° C. x = 77° y = 83° D. x = 87° y = 93°

Answer 1

All triangle's angles add up to 180 degrees
So....

67+36+x=180
103+x=180
x=180-103
x=77 degrees

All quadratic angles add up to 360 degrees
So....

63+112+102+y=360
277+y=360
y=360-277
y=83 degrees


Hope I didn't mess up for your sake.
