Question

please someone help.to find this both no.6,7

Answer 1

6. We know that: p°+q°+r°=180°

 It is given that: p°=q°=r°

so we can write: 3p°=180°

                            p°=60°

p°=q°=r°=60°

7. x=2y

  we know that : x+y=180°

                           2y+y=180°

                               3y=180°

                                y=60°

x=2y

x=2×60°=120°
