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

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
