What is the angle 0 in the triangle below? (hint: use the inverse trigonometric function.)

a. 33.6
b. 39.8
c. 0.83
d. 56.4

B. 39.8°

Explanation:

Since the adjacent and opposite sides are given, we use tan ratio for the triangle.

Using tan ratio for the given triangle, we get

Therefore, the correct option is option B.

anchor = archer //

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
