The question is related to trigonometry and we have to use the formula of double angle .
Here we use double angle formula of tangent function which is

Given expression is

Comparing it with double angle formula, we will get x = 5
SO the required expression is equal to


So the answer is tan(10) .
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:

From here, we clear the value of x.
We have then:




Answer:
4/9 divided by 1/27 equals 12
1. A = ¹/₂bh
A = ¹/₂(25)(4)
A = ¹/₂(100)
A = 50 yd²
3. A = ¹/₂bh
A = ¹/₂(3)(1)
A = ¹/₂(3)
A = 1¹/₂ cm²
