Answer/Step-by-step explanation:
1. The vertex of am angle is formed when two lines join together. The vertex of the angle shown in the diagram is located outside the circle.(<R)
2. The lines that created <FRT (lines FR & TR) are secants
3. The major arc = FT = 140°
minor arc = QS = 44°
4. Formula of Exterior angles of a circle = (major arc - minor arc)/2
x = (140 - 44)/2
x = 96/2
x = 48°
Answer:
I think the first one is power ( if not then coefficient) and the second is definitely expression
Step-by-step explanation:
2a²b³ and -4a²b³ are like terms as they both have the same variables with the same degrees.
Your final answer is a. True.

I'm not sure how to explain it
Answer:
The measure of arc AC is equal to 33°
Step-by-step explanation:
we know that
The inscribed angle measures half that of the arc comprising
so
∠ABC=(1/2) arc AC
substitute the values
(2.5x+4)=(1/2)(7x-2)
solve for x
5x+8=7x-2
7x-5x=8+2
2x=10
x=5
Find the measure of arc AC
arc AC=(7(5)-2)=33°
