Question

The hypotenuse of a right triangle measures 7 cm and one of its legs measures 2 cm. Find the measure of the other leg. If necessary ,round to the nearest teeth

Answer 1

in this case you would use pythagorean theorem. the hypotenuse is always c, and the other legs are a and b. the formula is:

c^2=b^2+a^2

plug in your numbers- 7^2=b^2+2^2

then you solve for b. the answer would be square root of 45, or 6.708 cm
