Sketch this triangle on a sheet of paper and find the values for all of the angles (m<a, and m<c) and the lengths of all the sides (length of AB and BC) The next 4 questions will ask you for these values.

Finding all of these angles and sides is called solving the triangle.

What is the measure of <A?

• 25 degrees

• 90 degrees

• 28 degrees
