Question

sin 30 degree minus sin 90 degree + 2 cos 0 degree by Tan 30 degree into tan 60 degree

Answer 1

hope it will be right

Answer 2

Given,

Sin 30 degree minus sin 90 degree + 2 cos 0 degree by Tan 30 degree into tan 60 degree

• Sin 30° = 1/2

• Sin 90° = 1

• Cos 0 = 1

• Tan 30° = 1/√3

• Tan 60° = √3

Now, the given problem

= Sin 30°-Sin 90°+2 cos 0°÷Tan

30°× Tan 60°

= 1/2-1+(2 × 1 ) ÷ 1/√3 × √3

= 1-2/2+ 2 ÷ 1

= -1/2 + 2

= 4-1/2

= 3/2

Therefore, the answer is 3/2
