The hypotenuse of a right triangle measures 13 cm and one of its legs measures 1 cm. Find the measure of the other leg.

12.69

Explanation:

Use pythagorus theorem which says a^2+b^2=c^2

where a^2 and b^2 are the legs of the triangle and c^2 is the hypothenuse

(Plug into the equation)

1^2+b^2=13^2

(solve the 1^2 and 13^2)

1+b^2=169

(Substract 1 from both sides)

√b^2=√168

(Finally take the square root of 168 *this is very important*)

b=12.96

Round the answer.
