you did not try reviewing your basic trig functions and drawing a diagram.
Look at the diagram and you will see that
cosθ = 7/20
The height h can be found from θ, since
h/20 = sinθ
or, you can use the Pythagorean Theorem (have you forgotten that already?):
h^2+7^2 = 20^2
A 20-ft ladder is leaning against a building. If the base of the ladder is 7 ft from the base of the building,
what is the angle of elevation of the ladder? (Round your answer to one decimal place.)
How high does the ladder reach on the building? (Round your answer to the nearest whole number.)
Someone please hep me I tried everything and can you give me the final answer THank you
