complementary are two angles that equal 90°.
so you take the angle measurements and add them together to make 90
5x+2+3x=90
then you do the opposite of what was done (adding 2) so you subtract 2 and you get 88.
8x+2=90
-2
what remains from the equation is:
8x=88
then again you do the opposite of what was done (multiplying 8 times x) so you divide by 8 and you get 11.
88/8= 11
what remains is:
X=11
but you’re not done yet!!
this is the measure for angle R:
m
so you replace the x with the answer that you got previously, and then you have
3(11)=33
the measure of angle R is 33°
