Question

Triangles below have AB=QR BC=RP CA=PQ where angle A=40degree and angle B=60degree compute angle C of triangle ABC and all angles of trianglePQR

Answer 1

Answer:

Make the ∆ congruent by sss

So <abc = <qrp , <bac = <rqt

And And the third angle also be congruent

Step-by-step explanation:

So since <b = 60 and < A = 40

By ang sum property of∆

<C = 180 - 60 - 40

< C = 80°

Since we proved congruent the ∆

< R = 40°

<Q= 60°

< P = 80°
