Question

ABCD is a quadrilateral inscribed in a circle:

What equation can be used to solve for angle B?

a. (x + 16) - (6x - 4) = 180
b. (x + 16) + (x) = 90
c. (2x + 16) + (x) = 180
d. (x + 16) - (x) = 90

Answer 1

If a quadrilateral is inscribed in a circle, then opposite angles are supplementary.

Answer 2

m<B + m<D = ? @lowcard2

Answer 3

180?

Answer 4

Yes.

m<B + m<D = 180

Substitute for the given angle measures and then determine which equation it is.

Answer 5

c. (2x + 16) + (x) = 180?

Answer 6

Yes, that is what I got.
