Question

$6 {x}^{2} + 17x + 5$
​

Answer 1

Answer:

1+ tan A

1+cot 4

Step-by-step explanation:

In AABC, right-angled at B, AB = 5 cm and ZACB = 30° then the length of the side BC

(a) 53 (b) 23

(c) 10 cm (d) none of these

atl t & 99

1/2

is

4. In AABC, right-angled at B. AB = 5 cm and ACB = 30° then the length of the side AC is (a) 53 (b) 213 (c) 10 cm (d) none of these

5. The value of

2 tan 30°

is

1+ tan 30° (a) sin 60° (b) cos 60°

6. The value of 1- tan 45° 1+tan 45 is

(a) tan 90° (b) 1 (c) sin 45° (d) 0

7. sin 2A = 2 sin A is true when A= (a) 0° (b) 30° (c) 45° (d) 60°

2 tan 30°

8. The value of 1- tan 30° is

(a) sin 60° (b) cos 60 (c) tan 60° (d) sin 30°

9. 9 sec A-9 tan' A (a) 1 (b) 9 (c) 8 (d) 0

10. (1 + tanA + secA) (1 + cotA - cosecA) = (a) 0 (b) 1 (c) 2 (d) -1

11. (sec A + tan A) (1 - sin A) = (a) sec A (b) sin A

12.

1+ tan A

1+cot 4 (a) sec A

(b)-1

(c)
