Step-by-step explanation:

Since you are trying to find the angle measurement, you must use the inverse of cosine: $cos^{-1}$ (you're using cosine because you have the opposite side and adjacent side):

$cos^-1(4/5)$

≈36.87

The height of a triangle is 4 m less than its base. The area of the triangle is 48 m².What is the length of the base?

yaroslaw [1]

Triangle Area = .5 * base * height

48 = .5 * (x +4) * x

48 = (.5x + 2) * x

48 = .5x^2 + 2x

.5x^2 + 2x -48 = 0

x = 8

base = 12
