Answer 1

Answer:

a=sqrt[50]; ?=50

Step-by-step explanation:

Using the Pytagorean theorem in the right triangle:

A^2+B^2=C^2, with A=a, B=a, and C=10

Replacing in the formula:

a^2+a^2=10^2

Adding like terms:

2a^2=100

Solving for a: Dividing both sides of the equation by 2:

2a^2/2=100/2

a^2=50

Square root both sides of the equation:

sqrt(a^2)=sqrt(50)

a=sqrt(50)
