hope that helps
Answer:
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
<u><em>The sentences that are true </em></u>
A) A and B are supplementary
First set everything to 0.
Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
Then it has to be either quadratic or cubic, I'm leaning more towards quadratic though
