What Is Tan D As A Fraction What Is Sin D To The Nearest Thousandth What Is Cos D To The Nearest Thousandth class=

Sagot :

tan D = 7/4

sin D = 0.864

cos D = 0.494

Explanation:

Tan ratio = opposite/adjacent

opposite = side opposite the angle D = 7

adjacent = base = 4

tan D = 7/4

sin ratio = opposite/hypotenuse

hypotenuse = 8.1

sin D= 7/8.1

sin D = 0.8642

To the nearest thousandth, sin D = 0.864

cosine ratio = adjacent/hypotenuse

cos D = 4/8.1

cos D = 0.4938

To the nearest thousandth, cos D = 0.494
