Which of the following is true for the rational function f(x)=x-4/x^2-16. a)the vertical asymptotes is x=4. b) the zero of the function is a 4. c)=the vertical asymptote is x=-4. d) the zeros of the function are 4 and -4.

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
