Answer:
Ginny made a mistake in step 1 when she identified b = 31. It should be b=-31
Step-by-step explanation:
Ginny factored as shown:
ac = –180 and
b = 31
36(–5) = –180 and 36 + (–5) = 31
+ 36x – 5x – 30
6x(x + 6) – 5(x + 6)
(x + 6)(6x – 5)
b is the coefficient of x and from the trinomial , b=-31.
Therefore Ginny made a mistake in step 1 when she identified b = 31. It should be b = –31.
The correct steps are: :
ac = –180 and
b = -31
36(–5) = –180 and -36+5 = -31
Answer:
The elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°

AB = height of the building = 250 feet
BC = 800 ft
Angle of elevation =
= 0.3125
°
Therefore the elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°
