Answer:
a = 60
b = 120
c = 120
Step-by-step explanation:
A has the same angle as 60 degrees
To find b
60 + b = 180
b = 120
C has the same angle as b
So c = 120

Answer:
- 5x² - 11x + 2
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x)
= - 4x² - 6x - 1 + (- x² - 5x + 3)
= - 4x² - 6x - 1 - x² - 5x + 3 ← collect like terms
= - 5x² - 11x + 2
