Question

Triangle ABC is congruent to triangle pqr if triangle is equal to 55 degrees then angle Q is equal to 65 degrees then find angle r

Answer 1

Answer:

60

Step-by-step explanation:

lets assume the last angle to be x

so,

x + 55 + 65 = 180

x + 120 = 180

x = 180 - 120

x = 60

x = last angle = 60
