Can you find x before I reveal the trick?

At first glance, this geometry problem looks like a simple triangle question — but the 45° angle, 60° angle and the length 30 make it much more interesting than it seems.

In this video, I’ll show you how to break the diagram down step by step and use trigonometryto find the missing length x without getting lost in unnecessary calculations.

The key is recognizing the right relationship inside the diagram. Once you see it, the whole question starts to fall into place.

Pause the video before the solution and give it a try yourself.
