X decreased by the square of nine
x - 9^2 = x - 81
Answer:
< Less Than and > Greater Than
This symbol < means less than, for example 2 < 4 means that 2 is less than 4. This symbol > means greater than, for example 4 > 2. ≤ ≥ These symbols mean 'less than or equal to' and 'greater than or equal to' and are commonly used in algebra. In computer applications <= and >= are used.

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°
