Angle C is an inscribed angle of circle P. Angle C measure (5x-7) and arc AB measure (2x). Find X

Andrei [34K]

Answer:

Step-by-step explanation:

Assuming that arc AB is where the inscribed angle meets the outside of the circle, then the rule is that the inscribed angle is 1/2 of the measure of its intercepted arc. For us,

$5x-7=\frac{1}{2}(2x)$

Solving for x:

2(5x - 7) = 2x so

10x - 14 = 2x and

8x = 14 so

x = 1.75

what are the steps to solve 3.5(c-8)+c=12.5? I already went on a different website and found out the answer is nine. I plugged i

LekaFEV [45]

3.5(c-8)+c = 12.5
⇒ 3.5c- 3.5*8+ c= 12.5 (distributive property)
⇒ (3.5c+ c) -28= 12.5
⇒ 4.5c= 12.5+ 28
⇒ 4.5c= 40.5
⇒ c= 40.5/ 4.5
⇒ c= 9

The correct answer is 9~
