Answer: You could have an infinite amount of triangles with these measurements.
Unless, you are missing something in the problem, there is not enough information that would narrow it down to a single triangle. Angle A is fixed and the height is fixed. However, Angle B and C could be anything as long as they formed a triangle and had side a of 15 in between them.
The answer is 358
235+100=335
335+20=355
355+3=358
It is 34 because 34*100 is 3400 so 3400/34=100
Let's say that f(x) = ax^2 + bx + c
if f(g(x)) = 9x^2 + 6x + 7:
a(3x + 1)^2 + b(3x + 1) + c = 9x^2 + 6x + 7
9ax^2 + 6ax + a + 3bx + b + c = 9x^2 + 6x + 7
Comparing the two equations, we can see that a = 1, b = 0 and c = 6, therefor f(x) = x^2 + 6
A statement to interpret the verticals line test would be if you have a function that would get hit twice(or more) by a vertical line then it is not considered a function
