Answer:

80°

Explanation:

we know angle R and angle Q are equal cause of the dashes

so

2x+30=6x-10

and then solve

30=4x-10

40=4x

10°=x

since they're equal just plug in X for one

2(10)+30= angle r

50° = angle r

we have two 50° angles and we know every triangle is 180°

so create the formula

angle r + angle q + angle p =180°

fill it in

50° + 50° + p = 180°

so angle p= 80°
