Answer:
Step-by-step explanation:
ABC is same as FDE
so AC = FE = 5ft
angle B = 28 deg
angle C = 90 deg
so A = 180 - B - C = 62
Answer:
y = (x - 2)² + 9
Step-by-step explanation:
To obtain the equation in vertex form use the method of completing the square.
Add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 + 13
= (x - 2)² + 9 ← in vertex form
