Find the measure of angle n

36

Step-by-step explanation:

The triangle at the top has an angle of 18. The other side will have the same angle, so combining them we will get 36. A triangle has an angle of 180, and 180-36=144.

A line is also 180 degrees, and 180-144 is 36.

Therefor the angle is 36 degrees.

gdp is the best phrase!

(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
