Question

Without using a protractor to measure exactly, choose the BEST possible measurement of the angle above.

A. 90°
B. 45°
C. 85°
D. 160°

Answer 1

Explanation:

The slanting line has a slope of approximately 1, so the angle this line makes with the horiz. axis is approx. 45 degrees.

Answer 2

B

Explanation:

It's not going to be a right angle. The two lines of a right angle are perpendicular. A is incorrect.

C is incorrect. 85o is pretty close to 90 degrees. That angle is nowhere's near that large.

D is incorrect. 160 degrees is nearly a straight line. The angle shown isn't.

That leaves B.

B looks to be 45 degrees and since the others are incorrect, B must be your answer.
