At which value of x does the function f(x)have a vertical asympote? check all that apply.

Answer

The answer is 49 degrees

Explanation

The exterior angle, the angle outside the triangle, it going to equal the angles inside the triangles.

w-19+w=w+30      Combine like term so combine the w's to be 2w

2w-19=w+30         Add 19 to both sides 30+19=49

2w=w+49              Subtract w from both sides 2w-w=w

w=49

To check your work you can plug 49 into w and you get that the angles inside the triangle is 79 and the exterior angle is 79 when you plug back in 79 and 79=79
