What is tan 3pi/4?

a. -1
b. |2|/2
c. -|2|/2
d. |3|/2

tan 3pi/4 is equal to -1

Given that we have to find value of

Let us evaluate the given expression

 ---- eqn 1

Substituting the values in eqn 1,

we know that by trignometric values,

Substituting these values we get,

Therefore,

Thus the value of tan 3pi/4 is -1

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
