Responses can also be moved by dragging with a mouse. By the triangle sum theorem, the sum of the angles in a triangle is equal to Response area. Therefore, m∠A m∠B m∠C=180°. Using the Substitution Property, (4x)° 90° (x 10)°=180°. To solve for x, first combine like terms to get 5x 100 = 180. Using the Response area, 5x = 80. Then, using the division property of equality, x = 16. To find the measure of angle A, use the Response area to get m∠A=4(16)°. Finally, simplifying the expression gets m∠A=64°.
