I'm not sure about what exactly your teacher is looking for, but the actual congruency conjecture you would use is:
(angle symbol) 1 (congruency symbol) (angle symbol) 8 - Because they are alternate exterior angles
Answer:
1. x = 4 and y = 1
2. x= 5 and y = 3
Use the examples below to complete 3 and 4.
Step-by-step explanation:
To solve each system of equations, use elimination.
1. Stack the equations and subtract to perform elimination.
2x + 2y = 10
- x + 2y = 6
-------------------------
x = 4
Substitute x = 4 into an equation to solve for y.
2(4) + 2y = 10
8 + 2y = 10
2y = 2
y = 1
2. Stack the equations and subtract to perform elimination.
3x + y = 18
- 2x + y = 13
-------------------------
x = 5
Substitute x = 5 into an equation to solve for y.
3(5) + y = 18
15 + y = 18
y = 3
Continue the same method for numbers 3 and 4.

Answer:
B. 44°
Step-by-step explanation:
Central angle = 3x + 10°
Inscribed angle = 2x - 17°
Now
Central angle = 2 * inscribed angle
( Central angle is double of the inscribed angle standing on same arc)
3x + 10° = 2 ( 2x - 17°)
3x + 10° = 4x - 34°
4x - 3x = 34 ° + 10°
x = 44°
Hope it will help :)❤
