11. f = 180-(75+65)
f = 180 - 140
f = 40°
12. x = 62+51
x = 113
y = 180- 113
y = 67°
13. x = 360-(100+95+60)
x = 360 - 255
x = 105°

Vertex form; y = 5(x - 3)² - 85
x-intercept; (3, +√17, 0) , (3 -√17, 0)
y-intercept; (0, -40)
minimum value at -85
range; [-85, ∞), {y|y ≥ -85}
hope this helps, God bless!
You have

apples left.
You have 5 whole apples, you took one whole apple out, which equals 4 whole apples left. Then with the whole apple you took out, you ate

of it.
Jack ate
of an apple in 5 apples. If you say that Jack ate

of 3 apples, then he ate

apples. So there isn't any difference when he ate

of an apple.
