35 degree angle the line passes through the 30 and 40

Step-by-step explanation:

so c

this would be 35degrees

Step-by-step explanation:

the angle is automatically under 90degrees. if you look at where the top line is it is in-between 30 and 40 making it 35 degrees

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.
