Answer:
130° is the answer to it
Step-by-step explanation:
180-50=130
Just use the Pythagorean Theorem
(9 +x)^2 = 15^2 + x^2
x^2 + 18x + 81 = 225 + x^2
18x = 144
x = 8
So the three sides of the triangle are
15, 8 and 17
Parallel would be anything with the slope of 4x and perpendicular would be anything with the slope of 1/4
