We have: 2/25= 24/?
Cross multiply:
2*?= 25*24
⇒ 2*?= 600
⇒ ?= 600/2
⇒ ?= 300
The length of the window is 300 ft~
Answer:
In right triangle hypotenus(side facing angle 90)is the longest
Step-by-step explanation:
lets say hyp=side1 +side2 were(side1=side2 in isocseles..) and Let x bet the length of side 1
So by applying phythegoras theorem :
hyp^2=x^2+x^2
16^2 =2x^2
2x^2=256
x^2=128
x=
Parameter=16+8
The answer would be<span>27 * 3/2 = 40.5</span>
