One of the legs of a right triangle measures 15cm and its hypotenuse measures 17cm. 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 15cm and its hypotenuse measures 17cm. Find the measure of the other leg. If necessary, round to the nearest tenth.Answer: □cm
Apply Pythagorean Theorem: To find the length of the other leg of the right triangle, we can use the Pythagorean theorem, which 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. The formula is a2+b2=c2, where c is the hypotenuse and a and b are the legs of the triangle.
Given Values: We are given that one of the legs a is 15 cm and the hypotenuse c is 17 cm. We need to find the length of the other leg b. We can rearrange the Pythagorean theorem to solve for b: b2=c2−a2.
Substitute Values: Substitute the given values into the equation: b2=172−152. This simplifies to b2=289−225.
Calculate Difference: Calculate the difference: b2=289−225=64.
Find Square Root: Find the square root of b2 to get the value of b: b=64=8cm.
