1. SAT Test Question (Isosceles)

I can't quite understand how to get the degree of the triangle the question asked for. If possible can someone spoon feed me on this one?

I will never do that.
But note that if $m\left( {\angle MAC} \right) = x$ then $4x=140$.
If you have trouble with that then you have a great deal of work to do to get ready for the SAT.

I believe I still have allot to learn to get ready for my nov-5 SAT. But I'm willing to learn as much as I can, my current classes are giving me allot of work. Anyways
x=35

Correct.

You now know that ${\angle MAC}=35^\circ$

What does ${\angle}AMC$ equal?

This is a very easy question.

Angle BAC = Angle BCA = (180 - 40)/2 = 70

So angle MAC = angle MCA = 35

now ,

70+ angle AMC = 180
So angle AMC = 110
