Does 10, 9, and 15 make a right triangle?
1 answer:
the triangle formed by sides 10, 9 and 15 units can't be a right angled triangle, because they doesn't form the pythagorean triplet, that is the sum of squares of the smaller sides isn't equal to the square of largest side,
sum of squares of smaller sides
=》
=》
=》
now, square of largest side (hypotenuse)
=》
=》
they aren't equal, proved

Answer:
C
Step-by-step explanation:
The right triangle on the right side of the figure has a height of 6 (two same sides lengths) and a base of 3.
x is the hypotenuse (side opposite of 90 degree angle).
We can use the pythagorean theorem to find x. The pythagorean theorem tells us to square each leg (height and base) of the triangle and add it. It should be equal to the hypotenuse square.
For this triangle it means, we square 6 and 3 and add it. It should be equal to x squared. Then we can solve. Shown below:
<em>Now we can use property of radical to simplify:</em>
Correct answer is C
