In 524.2, 5 is in the hundreds place, so it stands for 500. In 254.6, 5 is in the tens place, so it stands for 50. You know what place it is in by how far to the left or right it is from the decimal point.
<u>To solve this, we need to use our trignometric functions</u>;
⇒ <em>look at the diagram attached</em>

<u>Let's examine what the problem wants</u>:
- hypotenuse (<em>longest side)</em> of the triangle
<u>Let's examine what the problem gives us</u>:
- side adjacent to the 45-degree angle
- angle that has measure of 45-degrees
<u>Let's solve</u>:
<u>Answer: 7.1</u> (<em>rounded to nearest tenth)</em>

Hope that helps!
Do do this you divide the largest denominator by the smallest;
