What is the value of p?

Answer:
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
Answer:
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.
