Скачать или смотреть Geometry: Can You Find Angle ABC? | The Easiest Way to Solve This Triangle Question! | SAT, ACT Math

Can you find ∠ABC in this triangle problem?
At first glance, it looks tricky but with the right geometry concept, you can solve it in seconds without overthinking!

In this short and simple video, we’ll walk you through a step-by-step method to find the value of ∠ABC when the other angles are expressed in terms of x. You’ll see how easy it is once you apply basic angle relationships and a little bit of algebra!

What You’ll Learn:
✅ How to use the sum of angles in a triangle (180° rule)
✅ How to handle expressions with x inside geometry problems
✅ How to find one missing angle step by step
✅ A clean, logical way to explain your reasoning - great for exams!
