A straight angle is one full revolution.
A reflex angle is larger than a straight angle.
The measure of straight angle is 180°.

this option is incorrect

A straight angle is one full revolution.

Step-by-step explanation:

Straight angle = 180°

So, "A straight angle is one full revolution" is wrong statment

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
