Which statements can be used to justify the fact that two right angles are supplementary? check all that apply. a. a right angle measures 90°. b. if two angles are complementary, the sum of the angles is 90°. c. if two angles are supplementary, the sum of the angles is 180°. d. a complementary angle is one-half the measure of a supplementary angle. e. a supplementary angle is twice the measure of a complementary angle.

a and c. hope this helps

Step-by-step explanation:

answer: it's d

step-by-step explanation:

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.
