Question

If t=18 and r=12, find S. Round to the nearest tenth

Answer 1

The answer is 13.4 or √180

Pythagorean theorem states

${a}^{2} + {b}^{c } = {c}^{2}$

C^2 is the longest side. The corner of the right angle points to it. The other sides are your a and b squared. They are called the legs or Opposite and Adjacent sides.
