Answer:
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°

Answer:
The cubic polynomial is: x³ - x² - 6x.
Step-by-step explanation:
Given the degree and the roots of the polynomial we can find it.
An n - degree polynomial has n roots.
Here, given that the degree of the polynomial is 3 and three roots are given. Also, if (x - a) is a factor of a polynomial then x = a is a root of the polynomial. The converse is also true.
Since, the roots of the polynomial are given to -2, 0, 3 then it should have had the following factors.
(x + 2)(x - 0)(x - 3) = 0
Multiplying them we get:
⇒
which is the required cubic polynomial.
Hence, the answer.
