Answer:
x = 80°
Step-by-step explanation:
x is the measure of a central angle which is equal to the measure of the intercepted arc.
So, x = 80°
Measure the same distance from the first line to the next at at least three points on the line to get it parallel

Answer:
x^3 -14x^2 -6
Step-by-step explanation:
Your expression is the difference of two polynomials. The parentheses can be removed by using the distributive property. The minus sign outside the second set of parentheses applies to each term inside parentheses.
-5x^2 +3 +x^3 -9x^2 -9
Now, you can group like terms. In "standard form", the degrees of the terms decrease from left to right.
x^3 +(-5x^2 -9x^2) +(3 -9)
And combine like terms.
x^3 -14x^2 -6 . . . . . simplified form of the given expression
