I accept that θ in second quadrant, therefore sinθ > 0, cosθ < 0 and tanθ < 0.
We know that
first garden dimensions -------> <span>6 feet long x 4 feet wide
second </span>garden dimensions-----> (6*2) feet long x (4*2) feet wide
then
second garden dimensions-----> (12) feet long x (8) feet wide
[perimeter first garden]=2*6+2*4---------> 20 ft
[perimeter second garden]=12*2+8*2---------> 40 ft
[the percent of change in perimeter]=[[perimeter second garden]-[perimeter first garden]}/[perimeter first garden]
[the percent of change in perimeter]=(40-20)/20-------> 1---------> 1*100-------> 100 %
the answer is 100%

If you’re solving for x then X is 60 degrees
Answer:
x = 8
y = 12
z = 48
Step-by-step explanation:
Using CPCTC (Corresponding Parts of Corresponding Triangles are Congruent), we can set up two equations to solve for x and y...
3x=24
9y=108
Start by solving for x...
3x=24
Divide both sides by 3
x=8
Then, solve for y...
9y=108
Divide both sides by 9
y=12
Note that angles in a triangle add up to 180 degrees. We can use this information to set up an equation:
24+108+z=180
132+z=180
z=48
