Question

In a triangle pqr, angle p=60 degree and angle q = angle r find angle r

Answer 1

Answer:

angle q=angle r

and angle p=60

by angle sum property of triangle

angle p+angle q+angle r=180

60+angle q angle q=180. (angle q=angle r,)

2(angle q)=180-60

angle q=120/2

angle q=60=angle r

Answer 2

Answer:

see this answer

Step-by-step explanation:

the sum of all inter angle=180

p+r+q=180

60+r+q=180

r+p=180-60

r+p=120

take r and q as X

so

x+x=120

2x=120

x=120/2

x=60

so

r,p,q all equal 60
