In this problem, we are given with the length of 20 ft ladder and the angle of elevation of 30 degrees. Angle of elevation is defined as the angle that is bound between the horizontal and the inclined object, in which in this case is the ladder. The height to the top of the ladder from the roof can be determined using the sin function.
sin Ф = opposite / hypotenuse
The hypotenuse is the length of the ladder in this case.
sin Ф = height / length
sin 30 = h / 20
0.5 = h/20
h =20*0.5
h = 10 ft
Hence, the height of the ladder from the top of the roof is 10 ft.
Answer:
y = x +3
Step-by-step explanation:
When you examine the table, you see that each y-value is 3 more than the corresponding x-value. This is represented in the equation ...
y = x +3
Answer:
did they give u some initial numbers to substitute with or something?
The absolute value of -6 is the distance it is away from 0. The absolute value would be |-6| or |6| to show that the numeral is 6 spots away from 0.
