pcney angles, findxll-4 90. Solve to get the value of x.]5. If the angles (13x + 30)° and (5x + 6)° are supplementary angles, find the measures ofthese angles.Hint: 13x +30 +5x +6 180. Solve to get the value of r and hence find the measure of the angles]6. If an angle exceeds its complement by 20°, find the angle.7. If the supplement of an angle is three times its complement, find the angleg[Hint: Let the measure of the required angle ber. Then 180-r-3 (90-x)]8·The supplement of an angle is one-third of itself. Determine the angle and its supplement.9. Two complementary angles are in the ratio 2:3. Find the angles.10. Two supplementary angles are in the ratio 4:5. Find the anlan |
