Question

HELP ME PLEASE!

Find the measures of two supplementary angles.
m∠CDF=_____°
m∠EDF=_____°

Answer 1

Supplementary= 180 degrees.

So, they both equal 180 degrees together.

3(x+3)+ 2(3+x)= 180

Distribute.

3x+9+6+2x= 180

Combine like terms.

5x+15= 180

Subtract 15 on both sides.

5x= 165

Divide both sides by 5.

x= 33

Plug in x.

3(33+3)= 108

2(3+33)= 72

m<CDF= 108

m<EDF= 72

I hope this helps!
