Question

1. If ∆ABC~∆PQR measure of angle A is 100° ,measure of angle B is 50°. What is measure of angle R ? *​

Answer 1

Answer:

As ∆ABC and ∆PQR are similar

both of them have similar angles

sum of angles In a triangle is 180

then

let another angle is x

100+50+x=180

150+x=180

x=180-150

x=30
