Pls name the postulate or theorem you can sue to prove qts=srq

The correct option is 4.

Step-by-step explanation:

According to the HL postulate of congruent triangles, two right angled triangle are congruent if hypotenuse and a corresponding leg are congruent.

From the given figure it is clear that triangle QRS and triangle QTS are two right angled triangles.

In triangle QRS and triangle QTS,

                       (Common side and hypotenuse)

                        (Given)

Since hypotenuse and one corresponding leg of both triangles are congruent, therefore by HL postulate of congruent triangles both triangles are congruent.

Therefore the correct option is 4.

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.
