Answer:

80

Step-by-step explanation:

The three angles of a triangle add to 180 degrees.  One angle is 10, the second is a right angle( which is 90 degrees).  Let the third angle be x

10 +90 +x = 180

Combine like terms

100 +x =180

Subtract 100 from each side

100-100 +x= 180-100

x = 80

Use the x-intercept method to find all real solutions of the equation. -9x^3-72x^2+36=3x^3+x^2-3x+8
larisa86 [58]

-9x^3-72x^2+36=3x^3+x^2-3x+8                     Add 9x^3 to both sides.

-72x^2 + 36 = 3x^3 + 9x^3 + x^2 - 3x + 8       Add 72x^2 to both sides

36 = 12x^3 +   73x^2 - 3x + 8                           Subtract 36 from both sides.

0 = 12x^3 + 73x^2 - 3x - 28      

It does factor, but it is not very nice.

(x + 6.06)(x - 6.09)(x + 0.632)

If there is any kind of error please report it in a note below.
