Question

If 2 cos A=root3, find the value of 2 sin A + root3 tan A.​

Answer 1

Answer:

And is 2....

Step-by-step explanation:

2cos A = root 3

Cos A = root 3/2

Angle A =30°

So the

2SinA + root3 tanA

2Sin30° + root3 tan30°

1 + 1

2

Answer 2

Answer:

2

Step-by-step explanation:

2cos A = √3

Find 2 sin A + √3 tan A

To solve this question we must find the value of A first

To find A we use the first equation that is

2 cos A = √3

We divide both sides by 2 so the equation will look like this.

Cos A = √3/2

We find √3 using the calculator

Cos A = 1.73205 ÷ 2

Cos A = 0.8660

A = cos -1 0.8660

A = 30°

We substitute in the second equation

2 sin 30° + √3 tan 30°

2 × 0.5 + 1.73205 × 0.57735 =

1 + 0.999 = 1.99

When you round off you get 2.
