Question 1027453
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?
<pre>{{{2R = (1/2)*S}}} ----> {{{2R = S/2}}}_______4R = S ------ eq (i)
R + S = 90 ----- eq (ii)
R + 4R = 90 ---- Substituting 4R for S in eq (ii)
5R = 90
Measure of &#8736R is: {{{90/5}}}, or {{{highlight_green(18^o)}}}
