There are several ways to measure angles. Your calculator is set to measure in grads, of which there are 100 in a right angle instead of 90. You will need to change to either degrees or radians (whichever unit of measurement you are using in your class). You don't say what kind of calculator you have, so it's hard to tell you exactly how to make the change. Some calculators have a key that says "DRG". If you have such a key, pushing it repeatedly will switch between degrees, radians, and grads. On other calculators you need to go into the MODE or SETUP menu. One of the choices there should be different ways to measure angles.
