Please help answer for brainiest !:)

First, find angle AFE by using this equation:

42+90+ x=180

132+x =180

x= 180-132

x=48

Now, the angle AFE measures 48, and the angle DFE needs to be supplementary (they should both sum 180 degrees) so use this equation:

48+ x= 180

x= 180-48

x=132

This answer makes sense, because DFE is an obtuse angle (has more than 90 degrees).

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

correct answer:

i^31 = -i
