Question

Solve for the value of p.
(7p+7)°
33°

Answer 1

p=20°

Explanation:

(7p+7)°+33°=180°

7p°+7°+33°=180°

Step 1: Simplify both sides of the equation.

7p°+7°+33°=180°

(7p)°+(7+33)°=180°(Combine Like Terms)

7p°+40°=180°

7p°+40°=180°

Step 2: Subtract 40 from both sides.

7p°+40°−40°=180°−40°

7p°=140°

Step 3: Divide both sides by 7.

7p°/7°=140°/7°

p=20°
