Using the Pythagorean Theorem, the approximate values for x and y are given as follows:
c. x = 5.66, y = 8.
<h3>What is the Pythagorean Theorem?</h3>The Pythagorean Theorem relates the length of the legs and
of a right triangle with the length of the hypotenuse h, according to the following equation:
From the triangle to the right, we have that:
- The sides are x and
.
- The hypotenuse is of
.
Hence:
x² + 8 = 40
x² = 32
x = sqrt(32)
x = 5.66.
From the triangle to the right, we have that:
- The sides are both of
.
- The hypotenuse is of y.
Hence:
y² = 32 + 32
y² = 64
y = sqrt(64)
y = 8.
Hence option c is correct.
