Answer is 40. A triangle equals 180 so all you do is subtract 65 and 75 from 180 to get your answer.
I believe it is C, not 101% positive, but I think it is C
I believe you do 180 - 149 because it's a linear pair, it makes a t shape!!

What is a Quadratic Equation?</h3>
- Quadratic equations are the polynomial equations of degree 2 in one variable of the type where a, b, c, ∈ R and a ≠ 0.
- The standard form of a quadratic equation is .
Here, the given equation is
By comparing the given equation with the standard form of the quadratic equation we get,
a = 4
b = k
c = 4
The given quadratic is having one rational solution, which means
Therefore,
Therefore, the value of k is 8.
