Question

Triangle ABC has the angle measures shown. Measure of angle A = (2 x) degrees. Measure of angle B = (3 x) degrees. Measure of angle C = (4 x) degrees. Which statement is true about the angles? Measure of angle A = 20 degrees Measure of angle B = 60 degrees Angle A and Angle B are complementary Measure of angle A + measure of angle C = 100 degrees

Answer 1

Explanation:

step 1. 2x + 3x + 4x = 180° internal triangle angles add up to 180°

step 2. 9x = 180 or x = 20

step 3. <A = 2x = 2(20) = 40°

step 4. <B = 3x = 3(20) = 60°

step 5. <C = 4x = 4(20) = 80°.
