One of the legs of a right triangle measures 12cm and its hypotenuse measures 13cm. Find the measure of the other leg. If necessary, round to the nearest tenth.Answer: □cm
Q. One of the legs of a right triangle measures 12cm and its hypotenuse measures 13cm. Find the measure of the other leg. If necessary, round to the nearest tenth.Answer: □cm
Identify Known and Unknown: Identify the known sides of the right triangle and the unknown side we need to find. We know one leg a is 12 cm, and the hypotenuse c is 13 cm. We need to find the length of the other leg b.
Use Pythagorean Theorem: Use the Pythagorean Theorem to set up the equation for the right triangle.The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse c is equal to the sum of the squares of the lengths of the other two sides a and b.So, we have: a2+b2=c2.
Plug in Known Values: Plug in the known values into the Pythagorean Theorem.We have: 122+b2=132.
Calculate Squares: Calculate the squares of the known sides.122=144 and 132=169.So, we have: 144+b2=169.
Subtract to Solve: Subtract 144 from both sides of the equation to solve for b2.b2=169−144.
Calculate Difference: Calculate the difference to find b2.b2=25.
Take Square Root: Take the square root of both sides to solve for b.b=25.
Calculate Final Length: Calculate the square root of 25 to find the length of the other leg.b=5.
