Recall that two angles are supplementary if the sum of their measure is 180. find the measures of two supplementary angles if one angle is 20 more than four times the other

I don't know if it's correct

but I tried

Step-by-step explanation:

let the angle be x

20+4x+x=180

20+5x=180

5x=160

x=32
