Answer:
90
Step-by-step explanation:
Measure of one arc = 90°
-> Measure of other arc = 360°- 90° = 270°
x° = 1/2 (270° - 90°)
-> x° = 1/2 * 180°
-> x° = 90°
-> x° = 90°
-> x = 90
2x²-3x when x=-5
Plug in the value of x
2 (-5²) - 3(-5)
Simplify.
2 (25) +15
Simplify.
50+15
Simplify.
65 is your answer.
