Find the length of the uknown side round your answer to the nearest whole number.
1 answer:
Answer:
The length of the unknown side is 10 meters
Step-by-step explanation:
we know that
In this problem we have an isosceles right triangle
Applying the Pythagorean Theorem
where
c is the hypotenuse (unknown side)
a and b are the legs
we have
substitute
Round to the nearest whole number
therefore
The length of the unknown side is 10 meters

Answer:
see attached
Step-by-step explanation:
Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change) and "rise" (vertical change) between the marked points.
In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.
The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.
If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)
