Given:
A figure.
To find:
The pair of vertical angles.
Solution:
If two lines intersect each other, then they form 4 disjoint angles at the intersection point. From these 4 angles the alternative angles are known as vertical angles or vertically opposite angles.
In the given figure, the line TW and line SV intersect each other at R. So, the pair of vertical angles is and .
Therefore, the correct option is B.
Answer:
f(x) = - 2x³ - 11x² + 12x + 36
Step-by-step explanation:
given that x = a and x = b are the roots of a polynomial then
(x - a) and (x - b) are it's factors and the polynomial is the product of the factors
here x = -2 ( repeated ) and x = 3 (repeated), hence the factors are
(x + 2)² and (x - 3)² → the square denotes a repeated root
f(x) = (x + 2)²(x - 3)² ← expand factors and simplify
= (x² + 4x + 4)(x² - 6x +9)
= - 2x³ - 11x² + 12x + 36 ← is a possible equation
(-4,-2) It is the bottom left side of a coordinate plane.
X= -40/11
hopefully this helps
