Answer:
about 71.6°
Step-by-step explanation:
The relevant trig function is ...
Tan = Opposite/Adjacent
Here, the "opposite" side of the right triangle is the height of the tower. The "adjacent" side is the distance to the tower. Then if the angle is x, we have ...
tan(x) = 900/300 = 3
x = arctan(3) ≈ 71.6°
Megan's angle of elevation is about 71.6°.
Y = (1/4)x + 3 is the linear function.
When x = 0, the initial value is 3.
When x increases by 1, 1/4 is added to the previous value.
Answer: 5
Step-by-step explanation:
weekday hours x*2
weekend hours y*10
x+y=26
2x+10y=220
----------------------
x=26-y
2(26-y)+10y=220
52-2y+10y=220
8y=220-52
8y=168
y=168/8
y=21
x=26-21=5
x=5
The answer would be y=-4 and x=4, so pick which ever number/letter has this answer.
