How do I find the values of X and Y?

y = 45

x = 17

Step-by-step explanation:

the angles of the big triangle are (180-56)/2 = 62

so we know x+y = 62

wwe also have a right triangle. and the other two sides are congruent which means the angles are congruent. 90/2=45

so y = 45

x = 62-45= 17

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.

what are ur choices?
