Answer: DE= 15 m
Explanation:
Since, in ,
After applying, Pythagoras theorem,
Thus, m
Again, in and ,
( Right angles)
BD=BD ( common edges)
(BD makes the angle bisector of angle B.)
Thus, according to AAS condition-
So, DE=DF (CPCT)
Therefore, DE=DF=15m⇒DE=15 m
To solve this you have to use the Pythagorean Theorem. Which is a²+b²=c² CF,CD,and DF makes a triangle Substitute it in a²+8²=17² Add a²+64=289 Subtract 64 to get a alone a²=225 Square root it a=15

Answer:
L = 2w - 3
p = 264
2(L + w) = p
2(2w - 3 + w) = 264
2(3w - 3) = 264
6w - 6 = 264
6w = 270
w = 270/6
w = 90/2
w = 45
L = 2w - 3
L = 2(45) - 3
L = 90 - 3
L = 87
The length is 87ft, and the width is 45ft
