Question

On a recent test, Shawna was given the following problem:

A right triangle has side lengths 7 meters and a hypotenuse of 25 meters. The other side is labeled a.

Shawna's work is shown below:

1. a2+72=252

2. a2+14=50

3. a2=36

4. a=6 m

In which step did Shawna make an error?
Step 1. She incorrectly applied the Pythagorean theorem.
Step 2. She incorrectly squared the numbers.
Step 3. She incorrectly isolated a2
Step 4. She incorrectly solved for a.

Answer 1

Answer:

Step 2. She incorrectly squared the numbers.

Answer 2

The step in which Shawna made a mistake is in step 2 were she incorrectly squared the numbers.

What is the length of the other side?

In order to detremine the length of the other side, Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where:

• a = length
• b = base
• c = hypotenuse

a² + 7² = 25²

a² = 25²- 7²

a = √25²- 7²

a = √625 - 49

a = 24
