Answer:

Simplify :-

6. 2

7. (3x^2 -9x - 2)/(x^2 -3x -10)

8. (x +4)^2/(x -4)(x-2)

9. 4x/5(x -5)

10. 2(3x -5)/x^2 -4

11. 2

triangle :-

1.

sin A = 4/5

cos A = 3/5

tan A = 4/3

sin B = 3/5

cos B = 4/5

tan B = 3/4

2.

sin A = 1/3

cos A = (root 2)/3

tan A = 1/(root 2 )

sin B = (root 2)/ 3

cos B = 1/3

tan B = (root 2 )/1

3.

sin A = 1/(root 2)

cos A = 1/(root 2)

tan A = 1

sin B = 1/(root 2)

cos B = 1/(root 2)

tan B = 1

4.

sin A = 5/13

cos A = 12/13

tan A = 5/12

sin B = 12/13

cos B = 5/13

tan B = 12/5
