In the figure ABC is a triangle. BC is parallel to AE. If BC = AC, then what is angle CAE equal to? (angle at B is 65 degrees.)
Elementary MathematicsGeometry
- A20 degrees
- B30 degrees
- C40 degrees
- D50 degrees
Explanation
BC = AC gives base angles 65 degrees, so angle BCA = 50 degrees; BC parallel AE gives angle CAE = angle BCA = 50 degrees.
