Atruss is a structure used to support the roofs of houses. below is a picture of a truss with an enlargement of one right triangle. to the nearest hundredth inch, what is measure of x?

  19.80 in

Step-by-step explanation:

The Pythagorean theorem tells you ...

  28² = x² + x²

  28² = 2x² . . . . . collect terms

  28 = (√2)x . . . . take the square root

  28/√2 = x ≈ 19.79899 ≈ 19.80 . . . . . divide by the coefficient of x and round (dimensions are in inches)

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

there are infinitely many solutions.
