Question

the sum of the measure of angle p in the angle s is 140° the measure of degrees of angle p is represented by the expression 5x + 30 degrees the measure of angle s is 80° what is the volume of x

Answer 1

we have

P = 5x+30

S=80

and S+P=140

then:

$\begin{gathered} S+P=140 \\ 80+5x+30=140 \\ 110+5x=140 \\ 110+5x-110=140-110 \\ 5x=30 \\ \frac{5x}{5}=\frac{30}{5} \\ x=6 \end{gathered}$

answer: B. 6
