Question

Given:  Right △ABC△��� with m∠C=90∘ and m∠A=60∘; AC=22
Find:  BC

The diagram depicts a right-angled triangle labeled as triangle ABC. - **Vertices and Sides:** - Vertex A is the top angle of the triangle. - Vertex B is the bottom right angle. - Vertex C is the bottom left angle with a 90-degree marker, indicating it is a right angle. - **Angles:** - Angle CAB is labeled as 60 degrees. - Angle ACB is the right angle, 90 degrees. - **Shape:** - The triangle is oriented such that side BC is horizontal, and side AC is vertical. This representation is a basic example of a right-angled triangle with an interior angle of 60 degrees, often used to demonstrate properties of trigonometric relationships or the construction of 30-60-90 triangles.
