Two right triangles are graphed on a coordinate plane. One triangle has a vertical side of 4 and a horizontal side of 10. The ot
zvonat [6]
For the hypotenuses to be able to lie on the same line:

The tan of angle in both should be the same. That is the two triangles should be similar.

For the first triangle  tanθ  = 4/10 = 2/5

For the second triangle,  tanθ  = 12/30 = 6/15 = 2/5

Since both angles in the triangle are the same, hence, the hypotenuses of the two triangles could lie along the same line.

the length of a rectangle is 4in more than its width, and its perimeter is 34in find the length and width of the rectangle ​
Anna [14]

Let l and w be, respectively, the length and the width of the rectangle.

If the length is 4 inches more than the width, we have

l = w+4

Moreover, the perimeter of a rectangle is given by

2(l+w)

And we can substitute l=w+4 to get

2(w+4+w)=2(2w+4)=4w+8

We know that the perimeter is 34 inches:

4w+8=34 \iff 4w = 26 \iff w = \dfrac{26}{4}=6.5

Which implies

l=w+4=6.5+4=10.5
