Question

Q11. Two angles of a quadrilateral are of measure 50° and the other two angles are equal what is the measure of each of these two angles

Q12. Solve 8x-11-5x +3 = 2x +4-3x​

Answer 1

Answer:

11. 130°

12. x=7

Step-by-step explanation:

11. In a quadrilateral, all the angles equal 360°

∴ 50° + 50° + ∠x + ∠x= 360°

∴ ∠2x= 260°

∴∠x= 260°÷2

∴∠x= 130°

12. 8x-2x-5x +3x = 4 + 11

     2x= 14

     x= 14 ÷ 2

     x= 7
