Question

Angles R & S

Answer 1

R and S are complementary, so

R+S = 90

(7+3x) + (2x+13) = 90

7+3x + 2x + 13 = 90

5x + 20 = 90

keep going to solve for x

once you have x, you can use it to find angles R and S

Answer 2

I got x=14 but im unsure how to plug that in..

Answer 3

R = 7 + 3x

R = 7+3*14

R = 7+42

R = 49 degrees

Answer 4

you can do the same for S = 2x+13

or

you can subtract 49 from 90 (since the two angles add to 90)

Answer 5

oh, okay i get it now (:

Answer 6

that's awesome, glad you do
