Answer 1

Respuesta:

6. tan7x = cot3x

   7x + 3x = 90°

   10x = 90°

   x = 9°

7. sec(x-10°) = csc(9x+10°)

   x-10°+9x+10° = 90°

   10x = 90°

   x = 9°

8. tan(x+30°) = cot(5x+30°)

   x+30°+5x+30° = 90°

   6x+60° = 90°

   6x = 30°

    x = 5°

9. x+q = 30°+q

   x = 30°

10. 4x-10° = x+50°

    4x - x = 50° + 10°

    3x = 60°

    x = 20°

11. x+20°+3x+10° = 90°

   4x + 30° = 90°

   4x = 60°

   x = 15°

12. 2x+α+x-α = 90°

    2x + x = 90°

    3x = 90°

    x = 30°

13. 2x-8° = x+12°

    2x - x = 12° + 8°

    x = 20°

14. 5x-30° = 60°-4x

     5x + 4x = 60° + 30°

     9x = 90°

     x = 10°

15. x+20°+2x+40° = 90°

    3x + 60° = 90°

    3x = 30°

    x = 10°
