Answer 1

Answer:

Step-by-step explanation:4-1/2+1-2/root3

The whole divided by

2/root3+1/2+1

Ans- 4

Answer 2

so to solve this you need to know the value or sin , cos , sec , cosec , tan and cot at different angles

sin 30° = 1/2

tan 45° = 1

cosec 60° = 2/√3

sec 30° = 2/√3

cos 60° = 1/2

cot 45° = 1

so let's solve the upper area first

sin30° + tan 45° - cosec 60°

1/2 + 1 - 2/√3

√3+2√3-4/2√3

4√3-4/2√3

4(√3- 1)/2√3

now lowers side

sec30° + cos 60° + cot 45°

2/√3 + 1/2 + 1

4+√3 + 2√3 /2√3

4+4√3/2√3

4(1+√3)/2√3

...........

so the value of the equation is

√3-1 / 1+√3
