Answer:
Step-by-step explanation:
- The two given angles are complementary, it means they add to 90°
<u>Find x:</u>
- 2x + 10 + x + 8 = 90
- 3x + 18 = 90
- 3x = 72
- x = 24
<u>Find Y:</u>
- m∠Y = x + 8 = 24 + 8 = 32°
Answer:
b.the system of the equations has exactly one solution at(-4.3).
Answer:
Discriminant = 140
Step-by-step explanation:
a = -2, b = 6, c = 13
6² - 4(-2)(13)
36 + 8(13)
36 + 104
140
