Answer 2

Triangle Side Lengths

The lengths of the sides of the isosceles triangle are 7 cm and 12 cm. We need to find the length of the third side.

Using the Pythagorean Theorem: To find the length of the third side in an isosceles triangle, we can use the Pythagorean Theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Calculation: Let's denote the length of the third side as x. Since the triangle is isosceles, the third side is also the base of the triangle.

According to the Pythagorean Theorem: \[ 7^2 + x^2 = 12^2 \]

Solving for x: \[ x^2 = 12^2 - 7^2 \] \[ x^2 = 144 - 49 \] \[ x^2 = 95 \] \[ x = \sqrt{95} \]

Answer: The length of the third side (base) of the isosceles triangle is approximately 9.746 cm.
