Answer:
8
Step-by-step explanation:
This problem uses the pythagorean theorem. 15 squared plus 8 squared equals 17 squared.
Answer:
<h2>x = 8 and y= 12</h2>
Step-by-step explanation:
For x use the Pythagorean theorem:

<em>subtract 36 from both sides</em>

We know: x + y = 20. Substitute:
<em>subtract 8 from both sides</em>

If you divide both sides by -4 you get

So, you wrote the equation in the form y=kx, and in this form k is the constant of variation. So, the constant is -2.
you would have 9.375 pieces or 75/8 pieces, depends on how you look at it
We may draw a vertical that bisects the vertex angle and the shorter side of the triangle, to form a right-triangle with the measurements:
hypotenuse = 8
length = 1.5
We may then apply:
sin(∅) = P / H
sin(∅) = 1.5 / 8
∅ = 10.8 ≈ 11°
This is half of the vertex angle, so the vertex angle is:
11 * 2 = 22°
