1/7 + x = 2/3x
1/7 = 2/3x-x
1/7 = 2/3x - 1x
1/7 = -1/3x
-3/7 = x
The answer is A) the height of students

<h3>What are trigonometric ratios?</h3>
Trigonometric ratios are defined as the ratio of different sides of a right angle triangle with respect to one angle of the right angled triangle.
Length of the wire = Hypotenuse of the triangle = X
Base of the triangle = Distance from the bottom of the tower to the point where wire is attached on ground = 20 m
Angle b/w Hypotenuse and Base of triangle = 46°
cos(θ) = Base / Hypotenuse
cos(46) = 20 / X
X = 20 / cos(46)
X = 28.79 m
Hence, the length of the wire is 28.79 m.

Equation of line h is y=-2x-1
Slope is -2 (because it’s parallel)
so you have y=-2x+a
now you have to plug in the points it needs to pass through -9=-2(4)+a
do -2(4)
isolate a so then you would add the -8 to the other side
do the math of -9-(-8)
that’s how you get y=-2x-1
