Let’s tackle the angles first! Complementary angles add up to . Since angle is represented by and angle is , we can set up the equation:

Simplifying gives us:

So, the value of is indeed ; you’ve found the right answer!

Now, for all you trivia buffs out there! Did you know that the word “complementary” in math comes from the Latin word “complementum,” which means to complete? It’s a nod to how these angles complete each other to form a perfect right angle! Who knew geometry could have such a sophisticated flair?

And here’s a quick tip for your future angle adventures: always double-check your calculations, especially when it comes to angles—misplacing a degree can lead to folks seeing a whole different figure! Remember, a little attention goes a long way in the world of math!
