ABC has a right angle at c if the length of side AC is 10 and the measure of BAC is 22degrees what is the length of side BC

I'm assuming that the side length of BC would be 148 degrees. If you add the two degrees that you already have (which is 10 and 22), you would receive your other half. But you must subtract what you added with the sum of the triangle (which is 180 degrees). So 180-32 equals 148.

Now, to make sure you're correct you can simply just do addition.

10+22+148 = 180
