The hypotenuse of a right triangle measures 10cm and one of its legs measures 9cm. Find the measure of the other leg. If necessary, round to the nearest tenth.Answer: □cm
Q. The hypotenuse of a right triangle measures 10cm and one of its legs measures 9cm. Find the measure of the other leg. If necessary, round to the nearest tenth.Answer: □cm
Identify Known Sides: Identify the known sides of the right triangle.We know the hypotenuse c is 10 cm and one leg a is 9 cm. We need to find the length of the other leg b.
Use Pythagorean Theorem: Use the Pythagorean Theorem to set up the equation.The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse c is equal to the sum of the squares of the other two sides a and b.c2=a2+b2
Plug in Values: Plug in the known values into the Pythagorean Theorem.102=92+b2100=81+b2
Solve for b2: Solve for b2.b2=100−81b2=19
Take Square Root: Take the square root of both sides to solve for b.b=19b≈4.4 (rounded to the nearest tenth)
