I need this answer asap !! In DJKL, side JK measures 10.6 inches, side KL measures 7 inches, and side JL measures 5 inches. Based on the information that is provided, which could be a correct set of angle measures for these sides?
angle J = 23.2°, angle K = 33.5°, angle L = 23.2°
angle J = 23.2°, angle K = 33.5°, angle L = 123.2°
angle J = 123.2°, angle K = 23.2°, angle L = 33.5°
angle J = 33.5°, angle K = 23.2°, angle L = 123.2°

angle J = 33.5°, angle K = 23.2°, angle L = 123.2°

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.
