The solution to this problem requires the Pythagorean theorem which is
a^2 + b^2 = c^2
where
a,b = legs of the right triangle
c = hypotenuse of right triangle
Let's substitute the known values into the equation and solve
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169
b^2 = 144
b = 12
So the length of the 2nd leg is 12 cm.</span>
Answer:
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula 
. Pick two points on the line and substitute their x and y values into the formula, then solve. I used the points (-5,-4) and (0,-6):
So, the slope of the line is 
.
2) Next, use the point-slope formula 
to write the equation of the line in point-slope form. (From there, we can convert it to slope-intercept form.) Substitute values for the 
, 
and 
into the formula.
Since represents the slope, substitute in its place. Since and represent the x and y values of one point on the line, pick any point on the line (any one is fine, it will equal the same thing at the end) and substitute its x and y values in those places. (I chose (0,-6), as seen below.) Then, with the resulting equation, isolate y to put the equation in slope-intercept form:
The solution of the formula for E is given by:
E = 50m/L.
<h3>How to solve an expression for a variable?</h3>
To solve an expression for a variable, we have to isolate the variable.
In this problem, the expression is given by:
L = 50m/E
Hence we do the operations to isolate E, as follows:
LE = 50m
E = 50m/L.
