Answer:

your answers are correct

Step-by-step explanation:

A straight angle measures 180°. It looks like a straight line with the vertex as a marked point on the line.

A right angle is usually marked with a little square in the corner, as in diagrams 2 and 5. Diagram 2 also shows complementary angles, two angles that have a sum of 90°.

Supplementary angles have a sum of 180°, so can form a straight angle as in diagram 1.

An obtuse angle is one that has a measure greater than 90°. (If it is greater than 180°, it is called a reflex angle.)

An acute angle is one that measures less than 90°.

(3x^3-4x^2-5x+3)+(-4 - 6x^3+x^2 - 5x+5)
= 3x^3 - 4x^2 - 5x + 3 - 4 - 6x^3 + x^2 - 5x + 5
= -3x^3 - 3x^2 - 10x + 4
