Answer:
First option: 3
Step-by-step explanation:
To solve for side 'a', use the Pythagorean Theorem
<em>a² + b² = c² </em>
where "c" is always the longest side called the hypotenuse,
"a" and "b" are the two shorter sides called legs.
<u>Substitute </u><u>c = 5</u><u> (hypotenuse) and </u><u>b = 4</u>
a² + b² = c²
a² + (4)² = (5)²
<u>Square the numbers you know</u>
a² + 16 = 25
<u>Subtract 16 on both sides to isolate 'a'</u>
a² = 25 - 16
a² = 9
<u>Find the square root on both sides</u>
a = √9
a = 3
