Answer:
Step-by-step explanation:
you can use tan-1 to find x then use pythagorean theorem to find y
It is -1 I learned this so long ago
The value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.
<h3>What is an Equation?</h3>
An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given that;
- √( 1 + (25/144) ) = 1 + (x/12)
First, we square both sides
√( 1 + (25/144) ) = 1 + (x/12)
(√( 1 + (25/144) ))² = (1 + (x/12))²
1 + (25/144) = 1 + ( x²/144)
Collect like terms
1 - 1 + (25/144) = ( x²/144)
25/144 = x²/144
We cross multiply
25 × 144 = x² × 144
Multiply each sides by 1/144
x² = 25
x = √25
x = 5
Therefore, the value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.

Let's take two points so that we can get the equation of the line which goes through those points. P1 (-9, -2), P2 (3, -17):
So, y is the line which goes through the first and last points of the chart.
To proof that the rest of points go through the line as well, we will evalute each point
Since the evaluation of these points don't correspond to the values of the chart we can assure that the relationship is not linear
