R%2BS=180

2R=%281%2F2%29S
4R=S
Substituting,
R%2B4R=180
5R=180
R=36
So then,
S=4%2836%29
S=144

Twice the measure of angle R is one-half the measure of angle S. If R and S are complimentary angles, what is the measure of angle R?
2R+=+%281%2F2%29%2AS ----> 2R+=+S%2F2_______4R = S ------ eq (i)
R + S = 90 ----- eq (ii)
R + 4R = 90 ---- Substituting 4R for S in eq (ii)
5R = 90
Measure of ∠R is: 90%2F5, or highlight_green%2818%5Eo%29
