Question

who can solve Pythagorean Theorem

Answer 1

Answer:

a = 7.21

Step-by-step explanation:

Remark

This just uses a^2 + b^2 = c^2. You know 2 of the three things there.

Givens

• c = 14
• b = 12
• a = ?

Solution

a^2 + b^2 = c^2        Substitute the givens

a^2 + 12^2 = 14^2     Expand

a^2 + 144 = 196         Subtract 144 from both sides

a^2 = 196 - 144          Collect like terms on the right  

a^2 = 52                    Take the square root of both sides.

sqrt(a^2) = sqrt(52)    

a = 7.2111

a = 7.21                       Answer
