B is the answer
i simplified the theorem, but i hope this makes sense!
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
2x+8=20
2x=20-8
2x=12
12/2=x
6=x
Answer:
x>3/2
Step-by-step explanation:
Answer: Equation of st line is Y= -9X + 141
Step-by-step explanation: Given Y= 24 when X = 13 and Y = 87 when X = 6
Let the equation be Y = mX + C
24 = m*13 +C
and 87 = m* 6 +C
Give m = -9 and C = 141
Equation of st line is Y= -9X + 141
