Question

Triangle MNO is similar to triangle PQR. If angle N measures 85 degrees and angle P measures 75 degrees, what is the measure of angle R?

20

75

85

160

Answer 1

angle M = angle P = 75
angle N = angle Q = 85
so R = 180-P-Q = 180-75-85 = 20 degrees

Answer 2

thank you ^_^

Answer 3

Reciprocal angles are equal to each other in similar triangles. If ABC is similar to XYZ that means
angle of A = angle of X
... B = ...Y
... C = ... Z

Answer 4

thank you so much now i get it :) !!
