Remember that all the interior angles of a triangle add up to 180°.
The picture tells us two of the angles,
which is 40° and 
which is also 40°.
Subtract the measurement of these two angles from 180° to find the measure of the third angle,
:
180° - 40° - 40° = 100°.
The measure of angle RST is 100°.

Option C
The zeros of the polynomial function f(x) = x^3 - 5x^2 - 6x is x = 0 and x = -1 and x = 6
<h3><u>Solution:</u></h3>Given that polynomial function is f(x) = x^3 - 5x^2 - 6x
We have to find the zeros of polynomial
To find zeros, equate the given polynomial function to 0. i.e f(x) = 0
Taking "x" as common term,
Equating each term to zero, we get
Thus one of the zeros of function is x = 0
Now let us solve
We can rewrite -5x as -6x + x
Taking "x" as common from first two terms and -6 as common from next two terms
Taking (x + 1) as common term,
(x + 1)(x - 6) = 0
x + 1 = 0 and x - 6 = 0
x = -1 and x = 6
Thus the zeros of given function is x = 0 and x = -1 and x = 6
