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°

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
