Answer 1

Problem 1

It is either 130 or 50 depending on which way you are measuring. It looks to me like it is from R(ray) so 130 is the preferred answer.

Problem 2

I don't think the protractor has anything to do with the question. It is just a straight forward ratio question.

$\dfrac{1 inch}{2.5 miles}=\dfrac{3 inches}{x} \text{ cross multiply}$

x = 2.5 * 3

x = 7.5 miles

Problem Three

From Ray(R), Ray (S) is 10 degrees above R.
