Answer: 333.2ft
Step-by-step explanation:
We can draw a triangle rectangle, where the distance between the base of the building and the car is one cathetus (300ft)
The height of the building is the other cathetus.
Now, we know that the angle of depression from the top of the building to the car is 42°
This angle is measured from a perpendicular line in from the building, so the "top angle" of the triangle rectangle will be:
90° - 42° = 48°
if we steep on this angle, the 300ft cathetus is the opposite cathetus and the height of the building is the adjacent cathetus.
Here we can use the relation:
Tan(A) = Opposite cathetus/adjacent cathetus:
Then:
Tan(48°) = H/300ft
Tan(48°)*300ft = H = 333.2ft

Answer:
4 markers
Step-by-step explanation:
1/2 miles divided by 1/8 miles equals 4 markers.
1/2 ÷ 1/8
Apply the fraction rule:
1/2 × 8/1
Cross cancel common factor 2:
= 4/1
= 4

Answer:
b=r-9/9
Step-by-step explanation:
First you do the distributive property...
r=9b+9
then you subtract the 9
r-9=9b
then you divide the 9
r-9/9=b
and because of the symetry property you can flip it...
b=r-9/9
