I NEED HELP on THESE QUESTIONS EXCEPT ONE. Only do 2 and 3

201° and 60°

Step-by-step explanation:

(2)

∠ FHG = ( arc ES + arc FG ), that is

128° = ( 55 + FG ) ← multiply both sides by 2

256° = 55° + FG ( subtract 55° from both sides )

201° = major arc FG

(3)

The measure of the secant- tangent angle FTS is half the difference of the intercepted arcs, that is

∠ T = ( arc FS - arc US )

     = (170 - 50)°

     = × 120°

     = 60°

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.
