What is the angle relationship between angles 6 and 8?

Back

Supplemental angles are two angles whose measures add up to 180°.

Front

What is the slope of a line given the points (4, -8) and (6, -14)?

Back

Slope (m) = (y2 - y1) / (x2 - x1) = (-14 - (-8)) / (6 - 4) = -6 / 2 = -3.

Front

In a triangle, if angle 1 is 34° and angle 2 is 120°, what is the measure of angle 3?

Back

The sum of angles in a triangle is 180°. Angle 3 = 180° - (34° + 120°) = 26°.

Front
