Answer 10

complementary angles A and B add to 90 degrees.

\(\large\color{black}{ \displaystyle \angle{\rm A}+\angle{\rm B}=90^{\circ} }\)



supplementary angles C and D add to 180 degrees.

\(\large\color{black}{ \displaystyle \angle{\rm C}+\angle{\rm D}=180^{\circ} }\)

Answer 11

ok thank you!

Answer 12

so, say your "angle A" is 20 degrees, plug in 20 for A, and solve for B.
(this will be your complement angle)

Answer 13

and same way you can define "angle C" to be 20, and plug it into the equation for supplementary angles that I posted, and solve for "angle D".
(this will get you your supplement angle)
