Question

PLS HELP I REALLY NEED IT

Answer 1

A.)

Explanation:

5.7^2+3.2^2=42.73

Sqrt of 42.73=6.5

Answer 2

○=> Correct option :

`\color{plum}\tt\bold{(A) \: 6.5 cm}`

○=> Steps to derive correct option :

Given :

Length of leg in a triangle = 3.2 cm

Length of leg of another triangle = 5.7 cm

We know that :

`\color{hotpink}\tt {hypotenuse}^(2) \color{plum} = {base}^(2) + {height}^(2)`

Which means :

`= \tt {3.2}^(2) + {5.7}^(2) = {h}^(2)`

`=\tt 42.73 = {h}^(2)`

`=\tt √(42.73) = h`

`\hookrightarrow\color{plum} \tt6.5 \: cm= hypotenuse`

Thus, the hypotenuse of this triangle = 6.5 cm

Therefore, the correct option is (A) 6.5 cm
