Can these numbers be sides of a triangle?

No
If angle A of a triangle is 102, and an exterior angle connected to angle B is 137, what is the measure of angle C?
35
Can the sine of an angle ever equal 2? Why or why not?
No, the sine of a real angle can never equal 2. In any right triangle, the hypotenuse is always the longest side. Because the denominator (hypotenuse) is always larger than the numerator (opposite side), the fraction can never be greater than 1.
