Which equation can be used to find the measure of angle ljk? sin(x) = (10/15) sin(x) = (15/10) cos(x) = (10/15) cos(x) = (15/10)

we know that

In the right triangle LJK

m∠LJK°=m∠x°

in this problem

substitute

therefore

the answer is the option

The equation that can be used to find the measure of angle LJK is cos(x) = 10/15.

The image in the diagram is a right triangle. A right angle is a triangle that has an angle that measures 90 degrees. In the triangle, angle L measures 90 degrees. The hypotenuse is 15 inches.

Sin = opposite / adjacent

sin x = √(15² - 10²) / 15

sin x = 11.1 / 15

Tan = opposite / adjacent

tan x = 11.1 / 15

Cos = adjacent / hypotenuse

cos x = 10 / 15

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.
