What's the measure of angle RPS?

The answer is m∠RPS=23°.

Step-by-step explanation

Our goal is to solve m∠ RPS and hence we need to solve the unknown x.

We get the equation

180°=6x+11°+7x+143°,

noticing m∠RPS+m∠QPR=180° that is a straight angle.

Then solving the equation gives

180°=13x+154°

13x=26°

x=2°.

Finally replacement gives

m∠ RPS=6*2°+11°=23°.

The answer is m∠RPS=23°.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
