Question

Help me solve this pythagorean theorem please for 20 points

Answer 1

`b=2√(2)`

Explanation:

`a^2+b^2=c^2.`

`c^2-a^2=b^2.`

`3^2-1^2=b^2.`

`9-1=b^2.`

`b^2=8`

`b=√(8)`

`b=√(2(4))`

`b=2√(2)`

Hope this helps!

Answer 2

Length of perpendicular by pythagoras theorem :

P² = H² - B²

P² = 3² - 1²

P² = 9 - 1

P² = 8

P = 2√2
