Answer:
Step-by-step explanation:
We use trig to answer these questions:
sin x = opposite side of a triangle / hypotenuse
cos x = adjacent side / hypotenuse
Construct a right triangle with hypotenuse 4 m and lower angle 68 degrees.
The height of the top of the ladder is then defined by:
sin 68 degrees = height / 4 m, which yields (4 m)(sin 68) = height =
3.71 m
and the distance of the bottom of the ladder from the wall as follows:
cos 68 degrees = horizontal distance / hypotenuse =
1.50 m

Answer:
17.5
Step-by-step explanation:
You have to find n right?
9+4n-79 = 0
-> 4n = 70
-> n = 17.5
Answer:
x=4-5/3y
Step-by-step explanation:
3x+5y=12 make x on one side
3x=12-5y divide everything by 3
x=4-5/3y
