Given the figure, if ∠ABC is 20° and C is the center of the circle, what is the measure of the central angle ∠ACB? A) 40° B) 70°

kramer

Answer:

D) 140°

Step-by-step explanation:

The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.

Solve for x by factoring. Check your answers. Can you check to see if I'm correct?

Studentka2010 [4]

If you want to check if your answer is correct, expanding it all out will help!

(x-6)(x+2)=0 <-- Use FOIL tactic

x²+2x-6x-12=0

x²-4x-12=0

As you can see, this is identical to the initial equation given. The x values would be 6 and -2, as seen from the factored equation.

Hope I helped :)
