Angle x is the largest angle in triangle XYZ. Angle y is the smallest angle. How does the sum of the measures of angles y and z compare to the measure of angle x? Explain.
Well we could use the fact that the sum of the angles of any triangle gives 180 degrees, so we have: x + y + z = 180 y + z = 180 - x or x = 180 - y - z of course we cannot the actual values but this is an approach
