Not sure if i got these right can someone check my work

  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°.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

pretty sure 750 each month!
