(In the middle of a quiz, last question)

by Pythagoras theorem

(h)^2=(b)^2+(p)^2

13^2=5^2+(p)^2

169=25+p2

p2=169-25

p2=144

p=√144

p=12 answer

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

step-by-step explanation:

negitive slope
