Given tan A=-√5 and cos A >0, find sin A.
PLEASE HURRY AND SHOW WORK

sinA = -

Step-by-step explanation:

Given

tanA = - =

This is a right triangle with opposite = , adjacent = 1 and

hypotenuse h² = ( )² + 1² = 5 + 1 = 6 ⇒ h =

Since tanA < 0 and cosA > 0 then A is in the 4th quadrant where sinA < 0

Then

sinA = - = -

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
