Question

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

Answer 1

201° and 60°

Explanation:

(2)

∠ FHG =
`(1)/(2)`( arc ES + arc FG ), that is

128° =
`(1)/(2)` ( 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 =
`(1)/(2)` ( arc FS - arc US )

=
`(1)/(2)` (170 - 50)°

=
`(1)/(2)` × 120°

= 60°
