The value of x will be equal to x = 79.
<h3>What is the triangle?</h3>
Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
For an isosceles triangle, the value of two opposite angles is equal and the opposite sides are also equal.
The Sum of the three angles is equal to 180 degrees so the third angle will be calculated as:-
Angle = 180 - 142 - 19 = 19
Now applying Lami's theorem in the triangle we will get the third side.



x = 79
Therefore the value of x will be equal to x = 79.

Answer:
B
Step-by-step explanation:
The zeros of a polynomial are the solutions to the function. They are found from the factors. The factors which multiply to make the equation in standard form. To write the factors reverse the process by unsolving the factor.
x = -2 comes from x+2
x = 5 comes from x-5
x = 6 comes from x-6
The factored form is (x+2)(x-5)(x-6).
3 is the unit rate of 27 and 12
