Step-by-step explanation:
complementary angles means that both of them together = 90
13y +12 + 20y + 12 = 90
add all y together and numbers together
33y + 24 = 90
solve for y
33y= 66. y= 2
now let's get the measurements of the angles
13(2) + 12= 38
20(2) + 12= 52
Use this equation: A=3.14159r^2
x,z,y = 20,15,-33
i think thats it im sorry
The slope of the line would be 3/4
