Find x. Round your answer to the nearest tenth of a degree. (marking BRAINLEST)​

x = 47.2

Step-by-step explanation:

Since this is a right triangle, we can use  trig functions

cos theta = opp / hyp

cos x = 17/23

Taking the inverse cos of each side

cos ^-1 ( cos x) = cos ^-1 ( 17/25)

x =47.15635696

To the nearest tenth

x = 47.2

3/6   and 9/18

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
