length of side b? SHOW YOUR WORK
Answer:
C
b
B

Answer 1

Explanation:

If we assume that the triangle is a right-angled triangle, then we can solve this by using the Pythagoras theorem.

the Pythagoras theorem: a^2+b^2= c^2

We already have a= 57 inches and c= 121 inches

So, putting values in the formula:

57^2+b^2= 121^2

After simplifying we get:

3249 + b^2=14641

b^2= 14641-3249

b^2= 11392

Now, taking the square root of both sides, we would have b as:

b ≈ 106.7 inches

Answer 2

Explanation:

`a^2+b^2=c^2` (Pythagoras Theorem)

`57^2+b^2=121^2`

`b^2=121^2-57^2`

`b^2=11392`

`b=√(11392)`

`=106.73inches`
