What is tan(5pi/4) ? how do I solve

The value of is 1

Explanation:

Given that the expression is

We need to determine the solution of the expression.

Let us rewrite the angles for the expression

Thus, we have,

Simplifying, we get,

Multiplying by π, we have,

Since, we know that

Applying the above rule, we have,

Hence, simplifying, we have,

The value of is 1

Thus, the value of the expression is 1

36 is the final answer! : )

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
