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!
as given in the diagram this is equalatral triangle where all the side and angle are same
the sum of the three angle in a triangle is always 180 degrees
as in this triangle all of the angles are the same its
What you do is move the equation around so the 12 -4.5x would now turn into y=-4.5x+12
32x^10 + 18x^4 Hope this helps
