Need . problem: construct a triangle with interior angle measures of 45° and 45°. the third angle of the triangle is

The angles of a triangle add to 180 degrees so the remaining angle must be 90°.

This triangle is half a square. It's one of the two tired triangles of trig, the other being half an equilateral triangle, 30°/60°/90°.

(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
