Megan constructed triangle ABC. In Megan’s triangle, m∠A is represented by x°, m∠B is 4 times greater than m∠A, and m∠C is 30° less than 5 times m∠A.Choose the statements that are true about the triangle Megan constructed. Select all that apply.

The measure of ∠A is given as x°, so statement A is true. ∠B is 4 times ∠A, making it 4x°, and ∠C is 30° less than 5 times ∠A, making it (5x − 30)°; therefore C and D are true. The angles in a triangle add to 180°, not 360°, so E is false.
