The angle measurements in the diagram are represented by the following expressions.
ZA = 5z - 18°
ZB = 3x + 42°
Solve for x and then find the measure of ZA:

y=x+9

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

1) letter c.

2) 4 square root of 9
