The measures or the three angles of a triangle are x-39, x-29, and x. find the measure of each angle.

The three angles must add up to 180 degrees.

x - 39 + x - 29 + x = 180       Collect like terms on the left

3x - 68 = 180                        Add 68 to both sides.

3x = 180 + 68

3x = 248  

x = 248 / 3

x = 82.66667

Answer

x = 82,666667 for the largest angle

x - 29 = 53.666667 for the medium size angle

x - 39 = 43.666667 for the smallest size angle

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
