To solve this problem, you must know that an inscribed angle equals 1/2 of the arc that it intercepts.  

Therefore, because <ABC intercepts arc ADC, we know that

the measure of angle ABC = 1/2 * (measure of Arc ADC)

OR, when the values are substituted into the equation

165 = (1/2) (5)(x-3)

When simplified, this equation equals

330 = 5x - 15

345 = 5x

x = 69

Therefore, your answer is the second option, that x = 69 degrees.

X+2=-12<br><br> Help ASAP!<br> PLEASE!
Lena [83]

Hey there!

Answer = -14

Explanation:

Let's solve your equation step-by-step.

x + 2 = -12

Subtract 2 from both sides:

x + 2 - 2 = -12 - 2

x = -14

So therefore, that is how you found your answer: x = -14
