Hello,
Step-by-step explanation:
2x² - 7x - 15 = (x - 5) (2x + 3)
x - 5 = 0 ⇔ x = 5
2x + 3 = 0 ⇔ x = -3/2

Answer:
310°
Step-by-step explanation:
The sum of arcs around a circle is 360°.
MPN +MN = 360°
MPN = 360° -MN . . . . . . . . subtract MN
MPN = 360° -50° = 310° . . . fill in the given value
The measure of major arc MPN is 310°.
Answer:
