Find out if the lengths form a right triangle ​
Mila [183]

Answer:

The triangle is a right triangle.

Step-by-step explanation:

Since The Pythagorean Theorem only works on right triangles, we can use this knowledge to prove whether this triangle is right:

a^2 + b^2 = c^2\\10^2 + (2\sqrt{39})^2 = 16^2\\100 + (4 \times 39) = 256\\100 + 156 = 256\\256 = 256

Therefore, the triangle is right.

*please be serious*<br> 3y = -x - 12<br> *solve for y
Anna [14]

Answer: y=-\frac{1}{3}x-4

Step-by-step explanation:

To solve for y, we want to make sure y is isolated. SInce y is already isolated, all we need to do is divide both sides of the equation by 3.

3y=-x-12          [divide both sides by 3]

y=-\frac{x}{3} -4 or y=-\frac{1}{3}x-4
