Question

Which trigonometric function is being used if we get the fraction 6/10 as our answer? Question 3 options: sin(A) cos(A) tan(A) tan(gerine)

Answer 1

Answer:

cos(A)

Step-by-step explanation:

For angle A we have

opposite = 8

adjacent = 6

hypotenuse = 10

sin A = opposite/hypotenuse

cos A = adjacent/hypotenuse

tan A = opposite/adjacent

cot A = adjacent/opposite

6/10 = adjacent/hypotenuse = cos A

Answer 2

Answer:

cos A = 6/10

Step-by-step explanation:

That'd be cos A.  The cosine function is defined as the ratio

 adjacent side

------------------------

    hypotenuse

and here that ratio is cos A = 6/10.
