Question

Find an angle T on the unit circle such that 90º < T < 360º, tan T = tan U, and M angleU =81º.
a. 261°
b. 94°
c. 99°
d. 279°

Answer 1

are you getting the question?

Answer 2

a?

Answer 3

261

Answer 4

are you sure? : / what do you think mertsj

Answer 5

well yes i am surre

Answer 6

tan 81 is positive, so our tanT will have to lie in 3rd quadrant to be positive

Answer 7

We know that the tangent of 81 degrees is positive so the angle must be in the third quadrant since the tangent is only positive in Quadrants I and III and it can't be in one since the requirement is that it be greater than 90.
So it is a third quadrant angle with reference angle 81. When measured from the pole, it is 180 + 81 or 261

Answer 8

true...

Answer 9

okay thank you both . ! <3

Answer 10

and then tan(180+theta)=tanthetha put thetha = 81,,,, u will get d answer

Answer 11

i get so confused with tan and sin and cos
