There's a theorem for this: the angle made by two intersecting secants of a circle has a measure equal to half the difference of the arcs the secants intercept. In this case,
<em>x</em> = (130° - 30°) / 2 = 50°
Factor by grouping because there are 4 Terms
Answer:
10y + 15
Step-by-step explanation:
5(2y + 3)
= 5x2y + 5x3
= 10y + 15
So if you take 42/100 you get .42
Then you take .42 and multiply it by 28
Giving you the answer of 11.76
I'm no expert at math but i think it's C. 936,000,000
