Hey there! :D
We will use the properties of similar triangles to figure this out.
We will use two triangles inside the kite, with sides with the value of "x".
Smaller triangle:
Smaller side= 11
Bottom side= x
Bigger triangle:
Smaller side= x
Bottom side= 25

Cross multiply.
25*11= 275
x*x=

Find the square root.
√275= 16.583....
Or 5√11.
I hope this helps!

11a:
3x+5=5x-57
3x-5x=-57-5
-2x=-62
x=31
11b:
2x+2x+4x+150+4x+150=360
12x+300=360
12x=360-300
12x=60
x=5
hope this helped !!
Answer:
360-(124+124)= 360-248=122 divided by 4=30.5
A because -2 -3 -4 ext are less than -1
