Urgent math needed will mark brainliest look at the photo for the question and answer choices

The length of the new photo is 5in. This is because the width was reduced by 5in so you have to do the same thing to the length.  

Width:  8-3=5      

Length: 10-5=5

I hope this helped!

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
