Quadrilateral ABCD is inscribed in the circle. Which sentence is true?
A) A and B are supplementary
B) A and C are supplementary
C) m∠A = m∠B
D) m∠C = m∠D

A) A and B are supplementary

Step-by-step explanation:

we know that

For any inscribed  quadrilateral in the circle , opposite angles will be supplementary

so

In this problem

Angle A and Angle B are supplementary angles

Angle B and Angle D are supplementary angles

therefore

The sentences that are true

A) A and B are supplementary

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
