In △DEF, ∠F is a right angle. Find the remaining side and angles. e = 11, f = 15

d = 10.198 or 10.2

Step-by-step explanation:

Remember, the opposite side of the angle is the corresponding length. Meaning the length across ∠F would be f = 15.

If you were to physically draw the triangle, 'f' would be the hypotenuse.

Using Pythagorean Theorem,  or in this case, ,  plug in the given numbers.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
