Answer: b = [tex]\sqrt{7}[/tex], so you will enter 7
Step-by-step explanation:
The Pythagorean Theorem states that a² + b² = c² where a and b are the legs, and c is the hypotenuse.
All of these right triangles are congruent, so we only need to solve for one b.
Given:
a² + b² = c²
Input known values:
(3)² + (b)² = (4)²
Square:
9 + b² = 16
Subtract 9 from both sides of the equation:
b² = 7
Square root both sides:
b = [tex]\sqrt{7}[/tex]
