We need to sharpen our trig skills, because believe it or not, this problem involves trig!
Anyways, I assume we are allowed to use calculators.
What we need to do is calculate the tangent divided by 7. Maybe you haven't seen the wonders a calculator could do, so I will show you step by step.
1. Tangents!
2. Tangent(35)
3. 7 divided by that:
4. Enter!
There! Rounded, that would be 10
Maybe youll learn how to use calculators ;P, don't we all just love them?
