Answer:
D. 45
Step-by-step explanation:
<u>All angles</u><u> </u><u>h</u><u>a</u><u>v</u><u>e</u><u> </u><u>t</u><u>o</u><u> = 180°</u>
60 + 75 + <RVE = 180°
135 + RVE = 180°
180 - 135 = <u>4</u><u>5</u><u>°</u><u> </u><u>R</u><u>V</u><u>E</u>
<u>R</u><u>V</u><u>E</u><u> </u><u>=</u><u> </u><u>4</u><u>5</u><u>°</u>
<u>A</u><u>n</u><u>o</u><u>t</u><u>h</u><u>e</u><u>r</u><u> </u><u>w</u><u>a</u><u>y</u><u> </u><u>t</u><u>o</u><u> </u><u>c</u><u>h</u><u>e</u><u>c</u><u>k</u><u> </u><u>y</u><u>o</u><u>u</u><u>r</u><u> </u><u>a</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u>
Add all of the angles, and it should equal 180°
60 + 75 + 45 = 180°
Correct!

The x-intercept of an equation is the value of x when y is set to be equal to zero. On the other hand, the y-intercept is the value of y when x is set to be equal to zero. From the equation,
x-intercept : <span>3x - 9y = 10.8
3x - 9(0) = 10.8
x = 3.6
y-intercept: </span>3x - 9y = 10.8
3(0) - 9y = 10.8
y = -1.2
