Question

What is the value of b?​

Answer 1

Explanation:

2
`√(2)` is the hypotenuse

The other 2 sides are equal to b since this is a 45-45-90 triangle meaning that it's isosceles

`2b^(2)` = (
`2√(2)`
`)^(2)`

`2b^(2)` = (
`√(8))^(2)`

`2b^(2)` = 8

`b^(2)` = 4

b= 2

Hope this helps!!!

Sorry for taking so long

Answer 2

Answer: b = 2

Explanation:

`b = (2√(2))/(√(2) )\\b = 2`

Since this is a 45°-45°-90° triangle, the side opposite the 90° angle is √2× the other two angles. The other two angles are congruent since their opposite angles are both 45°.

Hope this helped! :p
