What is the value of p?

p = 28

Step-by-step explanation:

The sum of the angles of a triangle is always 180°. We can use this to set up an equation.

3p + 2p + 40 = 180

5p + 40 = 180

5p = 140

p = 28

p=28

Step-by-step explanation:

Knowing that three angles of a triangle add up to 180 degrees, you can come up with an equation specific to this problem,  3p+2p+40=180.

Combine like terms, you get, 5p+40=180

Then solve for p, 5p=140.

Divide─p=28 is the answer.
