Answer:
6.5 ft ft
Step-by-step explanation:
Angle L will be 180-90-76=14
Using the sine rule 
Relating to the above set up

Taking only the first two parts then

Therefore, rounded off to the nearest tenth, distance will be 6.5 ft
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:
57 degrees
Step-by-step explanation:
Answer:
The x coordinates and y coordinates will switch places with each other.
Step-by-step explanation:
A' coordinates will go from (x,y) to (y,x) so the coordinates will switch.
