Answer:
320 meters
Step-by-step explanation:
x² + 200x = 166400
It's a square, area should be side²
x² + 2(x)(100) = 166400
x² + 2(x)(100) + 100² = 166400 + 100²
(x + 100)² = 176400
x + 100 = 420
Since these are sides, we just consider the positive square root
x + 100 = 420
x = 320m
Using trigonometric ratio, the value of x is 63.6°
<h3>Trigonometric Ratio</h3>
This is the ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.
Trigonometric ratio are often coined as SOHCAHTOA
In the given triangle, we need to find the value of x using trigonomtric ratio.
Since we have the value of adjacent and hypothenuse, we definitely need to use cosine
cosθ = adjacent / hypothenuse
adjacent = 4
hypothenuse = 9
Substituting the values into the equation;
cos θ = 4 / 9
cos θ = 0.444
θ = cos⁻¹ 0.4444
θ = 63.6°

The steps to solving an inequality are: add or subtract from each side - multiply or divide both sides - simplify.
5x + 8 > -12
5x > -12 - 8
5x > -20
x > -20/5
x > -4
The answer is: x > -4
Answer:
IDK
Step-by-step explanation:
There is no problem to solve
<span>10x+4=7(6x-14)
10x+4=42x-98
-4 -4
10x=42x-102
-42x -42x
-32x=-102
/-32 /-32

I'm almost positive that this is correct if I multiplied wrong please do it right but this is a more general idea of how to solve it.
