(Since the perimeter is the length of each sides added up. Two sides are equal to x+6 and two are equal to x-6)
2 (x+6) + 2 (x-6) = 48
(break out the brackets)
2x + 12 + 2x -12 = 48
( 12 and -12 cancel out and "disappear".)
2x + 2x = 48
4x = 48
(Rearrange for x)
x = 48 / 4
x = 12 inches

Reactivity is chemical speciality
Answer:
40°
Step-by-step explanation:
We can find the tangent of ∠J using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering triangle ΔJKL, where ∠L=90°, JK = 7.3 feet, and KL = 4.7 feet
As such, with respect to angle J, JK is the hypotenuse, KL is the opposite side
Hence
Sin J = 4.7/7.3
Sin J = 0.643835616
J = 40.08°
Answer:
15ft
