Answer:
83
Step-by-step explanation:
the angle with 126 is supplementary and all the angles of the triangle are supplementary
180-126 = 54
54 + 43 = 97
180 - 97 = 83
Correct answer is D).
A) and C) are polynomials, so x∈R, in B) we have √x, and in this case x ≥ 0.
earnings * 20 percent = 17
earnings * .2 = 17
divide by .2 on each side
earnings = 17/.2
earnings = $85.00
