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!
Let student tickets are x and adult tickets are y
x + y = 516.........x = 516 - y .........(substitute in 2)
3x + 5y = 2046 ......(2)
3(516-y) + 5y = 2046
1548 - 3y + 5y = 2046
2y = 498
y = 249
x = 516 - y = 516 - 249 = 267
so the correct answer is b
