Answer:

y = (√7)/4

Step-by-step explanation:

The equation of the unit circle is ...

x^2 +y^2 = 1

Putting the given value in for x, we can find y to be ...

(-3/4)^2 +y^2 = 1

y^2 = 1 -(-3/4)^2 = 1 -9/16 = 7/16 . . . . . subtract 9/16

y = √(7/16) . . . . . . . . . . . take the square root; y > 0 here

y = (√7)/4
