Answer:
cosx = sqrt(15)/4, -sqrt(15)/4
Step-by-step explanation:
cos²x = 1 - sin²sin x
cos²x = 1 - (1/4)²
cos²x = 15/16
cosx = sqrt(15)/4, -sqrt(15)/4
Yes I think she is because y = f(x) = a + bx.
All you need for a linear function is one independent variable and one dependent variable, and you have that.
Hope this helps, sorry if not, have a good day. c;
Only one, if you want to know the measurement of the other side use the cosine law and to know the other angles use the sine law :)
