Answer: a=mx+b
Step-by-step explanation:
Answer: 74.6
we draw a right triangle ABC, have: ∠ABC = 90°, AB = 20 and ∠BAC = 75°, the height of the building is BC
we also have: tan 75° = BC/AB = BC/20
=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6
Step-by-step explanation:
4.5x+7.05y=$43.65
x+y=8
Timed 4.5 for both side to get
4.5x+4.5y=36
4.5x+7.05y=43.65
-
4.5x+4.5y=36
=
2.55y=7.65
y=3 pounds
x=5 pounds. Hope it help!
