The Pythagorean theorem tells you ...

... c² = a² + b²

... 13² = 12² + b² . . . . . fill in the given numbers

... 169 - 144 = b² . . . . .subtract 12²

... √25 = b . . . . . . . . . take the square root

... b = 5 . . . . . . The value of b you're looking for.

_____

The numbers {5, 12, 13} make what is called a "Pythagorean triple" a set of integers that satisfies the relation of the Pythagorean theorem. These, and the triple {3, 4, 5} are often seen in algebra problems. It can be worthwhile to remember these numbers.

A mirror is in the shape of an isosceles right triangle and has a hypotenuse length of seven times the square root of two. What
frez [133]

The length of one of the legs  of an isosceles right triangle and has a hypotenuse length of seven times the square root of two is 7 units.

<h3>What is an Isosceles triangle?</h3>

Isosceles triangles are triangles that has two of it sides equal to each other. The base angles of an isosceles triangle are equal.

The  isosceles triangle is also a right angle triangle. The hypotenuse is the longest side of a right angle triangle.

Therefore,

hypotenuse = 7(√2)

let the length of the other legs = x

Therefore, using Pythagoras theorem

c² = a² + b²

(7(√2))² = x² + x²

49 × 2 = 2x²

98 = 2x²

x² = 98 / 2

x = √49

x = 7 units
