420 is your possible rounded answer, the real answer to the problem is 225, but you said it needs to be rounded
The <em><u>correct answer</u></em> is:
90° clockwise
Explanation:
Comparing the image points to the pre-image points, we can see that in every ordered pair, x and y have been switched and x has been negated. Algebraically, this means (x, y)→(y, -x).
This is the same mapping that a 90° clockwise rotation performs, so that is our answer.
Answer:
Step-by-step explanation:
Angles 1 and 2 have common side, so they are adjacent. They are not making a right or straight angle.
Correct choice is D
Use the pythagorean theorem. It would be set up as
a^2 + 3.7^2 = 4.0^2
