If g ll h and m 1 = 55°, what is m 26?

answer:

The measure of angle 6 would be 125º.

Step-by-step explanation:

If you know that the measure of angle one is 55º, then angle 4 would also equal 55º because of the vertical angles theorem. The measures of angle 4 and 6 add up to 180º since same side interior angles on a transversal are supplementary(add up to 180º). Then, you subtract the mesure of angle 4 from 180º, and your answer is 125º(180-55 = 125).

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.
