A quadrilateral ABCD has the given angle measures. Select all measurements which could come from a cyclic quadrilateral.

A:
angle A is 90°, angle B is 90°, angle C is 90°, and angle D is 90°

B:
angle A is 80°, angle B is 80°, angle C is 100°, and angle C is 100°

C:
angle A is 70°, angle B is 110°, angle C is 70°, and angle D is 110°

D:
angle A is 60°, angle B is 50°, angleC is 120°, and angle D is 130°

E:
angle A is 50°, angle B is 40°, angle C is 120°, and angle D is 150°

A:  angle A is 90°, angle B is 90°, angle C is 90°, and angle D is 90°

B:  angle A is 80°, angle B is 80°, angle C is 100°, and angle C is 100°

D:  angle A is 60°, angle B is 50°, angle C is 120°, and angle D is 130°

Step-by-step explanation:

The sum of opposite angles of a cyclic quadrilateral is 180°

It must satisfy the following:

A+C=180° and B+D=180°

Only choice A and B and D satisfy.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m
