Pythagorean Theorem:
a^2 + b^2 = c^2
10. 144 + 196 = 340
Yes, it is a right triangle
11. 256 + 361 does not equal 684 so it is not a right triangle

Answer:
<h2>12x - 20y = -9</h2>
Step-by-step explanation:
The standard form of an equation of a line:

We have

Convert
<em>multiply both sides by 10</em>
<em>subtract 24x from both sides</em>
<em>change the signs</em>
<em>divide both sides by 2</em>

Area = (h/2)(a +b)
where h = distance between the 2 parallel line segments and a and b are the lengths of these 2 line segments.
