If F (X)equals X^3 - 2X^2, which expression is equivalent to f(I)

-1

Step-by-step explanation:

Plug in one to the equation to get (1)^3 - 2(1)^2, 1 to the power of anything is 1 so it boils down to 1-2, which is -1

The missing angle to this triangle is 55 degrees, x is 14.65, and the other missing length is 8.4.

Step-by-step explanation:

In a triangle, all of the angles sum up to 180 degrees. We are given it is a right triangle with another given angle of 35 degrees. 180 degrees - 90 degrees - 35 degress is 55 degrees. Now, we can use law of sines to find x. x / sin 90 degrees = 12 / sin 55 degrees. sin 90 degrees can be simplified to 1. x = 12 / sin 55 degrees. x = 14.65. By using the pythagorean theorem, we can find the last missing side, which is 8.4.
