If angle A =90 degree , b=1 cm and a =2 cm then solve the following right angled triangle ABC

Angle A = 90 degrees, side a = 2.Angle B = 30 degrees, side b = 1.Angle C = 60 degrees, side c = .

Side c:

If angle A is 90 degrees, side a is the hypotenuse. <--- this is NOT the correct way to write the Pythagorean theorem. I changed it to fit the side lengths. Normally, it is , where c is the hypotenuse. Since a is the hypotenuse, I switched the variables.

Finding the angles:

In a 30-60-90 right triangle, the...Shortest leg = xLongest leg = Hypotenuse = 2x In this case, the shortest leg is 1, the longer leg is (or ), and the hypotenuse is 2 (or ).As a result, this is a 30-60-90 triangle -- angle B is 30 degrees while angle C is 60 degrees.
