Question

How do i find the height (y inches)? Plz Plz Plz Plz help!!!!!!!!! plz

Answer 1

Firstly, you need to find the x length in inches by using the Pythagorean theorem.


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

`x^2+6^2=8^2`

`x^2=64-36`

`x= √(28)` [approx. 5.3 inches]

To find side y,

`y^2+5.3^2=7^2`

`y^2=49-28.09`

`y= √(20.91)` [approx 4.6 inches]

Answer 2

a^2 + b^2= c^2a​2​​ + b​2​​ = c​2​​
x^2 + 6^2= 8^2x​2​​ + 6​2​​ = 8​2​​
x^2 = 64- 36x​2​​ = 64 − 36
x= \sqrt{28}x=√​28​​​ [approx. 5.3 inches]

Now

To find side y,
y^2+5.3^2=7^2y​2​​+5.3​2​​=7​2​​
y^2=49-28.09y​2​​=49−28.09
y= \sqrt{20.91}y=√​20.91​​​ [approx 4.6 inches]

I think is correct
