Answer:
Angle 2 is congruent to angle 3
Angle 3 is congruent to angle 7
The answer is 80 arc cb has the same measures as the central angle
Answer:
x = 1 and x = -7
Step-by-step explanation:
Given that,
...(1)
and
y = 7 -x ....(2)
Put the value of y from equation (2) in (1)

So,
x = 1 and x = -7
Hence, the solution of the given equations is x = 1 and x = -7
You do 1/2 of the height and multiply the width
X:{a, b, c}, because the numbers(or letters in this problem) cannot repeat.
