Vertical angles is the same angle, but we don't know "x". If you look in a way. We can do 180=(3x+80).
100=3x
100/3 = x
Now we have the answer for x we plug it in to get the answer.
3(100/3) + 80 =<D
<D = <C
If you're trying to simplify, 3 5/8+ 2 7/8 = 6 4/8. So 10 1/8 + 6 4/8 is 16 5/8
Hey there! :)
All you have to do is divide the numerator(top number) by the denominator(bottom number).
17 ÷ 8 = 2.125
Rounded to the nearest hundredth = 2 places after the decimal point.
After the 2 is a 5. If it's 5 or greater, you move it up by 1.
2 + 1 = 3
2.125 = 2.13
Your answer is A ⇒ 2.13
Hope this helps :)
