Question

Help me pls gang!!!!

Answer 1

the angle is flat, measures 180°, the sum of the 2 angles = 180°

we put the equation

5p+7+4p+2= 180

9p+9=180

9p = 180-9

p = 19°

we calculate the measure of the angles:

5p+7 = 5*19+7=102°

4p+2 = 4*19+2=78°

Explanation:

Answer 2

p = 19

Explanation:

(5p + 17)° and (4p + 2)° are a linear pair and sum to 180°

sum the 2 angles and equate to 180

5p + 7 + 4p + 2 = 180

9p + 9 = 180 ( subtract 9 from both sides )

9p = 171 ( divide both sides by 9 )

p = 19
