8. in δrst, m∠r = (2x + 10)°, m∠s = (2x + 25)°, and m∠t = (x – 5)°.
what is the value of x?

6 meters

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
