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
You would do 14*4 which equals 56 so if you did that to every side you would get the number of the bigger shape so you would to find x is 3*4 which equals 12 so the answer is x=12
Its 30, i multiplied 6x5 and got 30 so im sure its the answer
Answer:
Errm please where is the angle of elevation
I think there should be an angle before we can find the height of the building
