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]

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
