Best ResponseYou've already chosen the best response.0The orthocenter is where the altitudes meet. Based on that, can you tell me where the orthocenter is?

Best ResponseYou've already chosen the best response.0Well, the 5x+55 is at a right angle. So, the equation you want to solve for x is 5x + 55 = 90 since it's a right angle.

Best ResponseYou've already chosen the best response.0Ok, GD = 2x  9, yes. However, to solve for GD, we need to solve for what 'x' is to plug in. The only information that lets us solve for what x is that 5x5 + 55 is a right angle. This means that \(5x+55=90\). Can you solve for what \(x\) is?

Best ResponseYou've already chosen the best response.0There you go. Now, you can plug it into GD to solve for GD.

Best ResponseYou've already chosen the best response.0Not quite. You solved for what x is. However, GD = 2x  9. So now, you need to plug in what x is. So, evaluate: \(2(7)9\).

Best ResponseYou've already chosen the best response.0Yes. And you know that the orthocenter is outside of the triangle because CDE is an obtuse triangle, which means the altitudes intersect outside of the triangle. Good job.
