Question

Solve for x. Assume that lines which appear to be diameters are actual diameters.

Answer 1

D

Explanation:

(x + 65)° is the central angle, the size of which is equal to the arc on which it rests:

`x + 65 = 60`

Collect like terms (don't forget, when moving terms to the other side, make sure to change their sign to the opposite of the previous one):

`x = 60 - 65`

`x = - 5`
