Solve for x. Round to the nearest tenth. Please help

answer is 64x68

Step-by-step explanation:

Step-by-step explanation:

take 38 degree as reference angle

using sin rule

sin 38=opposite/hypotenuse

0.61=x/13

0.61*13=x

7.93=x

8=x

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.
