In a circle, the internal vertical angles have a formula of

In this case, the formula would be:

We know that whole circle is 12x. And 12x is equal to 360°. When we put that into equation:


If x is 30°:

So, angle 7 is 90°.
B, eight more than five times a number because you would multiply 5 times n first due to the rule of pemdas
Answer:
77.18%
Step-by-step explanation:
115:149*100 =
(115*100):149 =
11500:149 = 77.18
Regroup terms:
y - 2/9 ≤ 5/9
Add 2/9 to both sides:
y ≤ 5/9 + 2/9
Simplify 5/9 + 2/9 to 7/9:
y ≤ 7/9
