Answer:
Step-by-step explanation:
17 = -13 - 8x....add 13 to both sides
17 + 13 = -13 + 13 - 8x
30 = -8x...now divide both sides by -8
-30/8 = (-8/-8)x
-30/8 = x.....reduce
- 15/4 = x <===
Explanation:
add 13 to both sides of the equation.
17+13=−8x.
30=−8x.
divde both sides by −8.
30−8=x⇒x=−308=−154.
As a check.
x = 12
Angle QPR + Angle PQR = Angle HRQ
Answer: 12
A polynomial is an expression that contains more than one number, letter, etc. so 12 is a monomial, because it only has one number. Hope this helps!!
it also measures 84° because 3is alternate angle to 6
