Given ADEF, which is not equal to cos(F)?
sin(F).
sin(D).
tan(F).
COS(D).
Answer:
tan(F)
Step-by-step explanation:
This is an isoceles triangle, both sides are the same so both the angles are the same as well. The sine and cosine of angles D and F are going to be the exact same because of the same sides. The only one that would be different would be the tangent of F or D.
The question is an illustration of an isosceles right triangle
The function that is not equal to cos(F) is tan(F)
From the figure, we can see that the triangle is an isosceles right triangle
This means that:
cos(F) = sin(F) = cos(D) = sin(D)
The odd option from the list of given option is tan(F)
Hence, the function that is not equal to cos(F) is tan(F)
