Item 1
angle a and angle b are supplementary angles.

what must be true about the angles?

the sum of the angles is 180°.

the angles were formed by two intersecting lines and are on opposite sides.

the sum of the angles is 90°.

the angles share a common side and vertex.

The sum of the angles is 180°.

Step-by-step explanation:

If Angle A and angle B are supplementary angles.

Supplementary means they add to 180 degrees.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
