Find where the graph crosses the X axis
ex: graph crosses X axis at x=2 and x=6
factorization should be (x-2) and (x-6) for a quadratic

Answer: The expression is 7/2.
Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° =
= 
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x =
≈ 88.2
