Question

Write the ratios for sin A and cos A.

Answer 1

sine A = opposite / hypotenuse
sine A = 63 / 65

Answer 2

Cos A = Adjacent / Hypotenuse
Cos A = 16 / 65

Answer 3

thank you and yes i copied down the sin cos tan now so i know it

Answer 4

ur welcome :)

Answer 5

do you think you can help me with another one?

Answer 6

sure :)

Answer 7

okay :)

Answer 8

Describe the vector as an ordered pair. Round the coordinates to the nearest tenth.

Answer 9

Create an altitude to form a y component j.

Solve for x component i and y component j, putting your results in the form

vector v = x i + y j

or

vector v = <i, j>

so

vector v = <54cos(69°), 54sin(69°)>

factor out the 54 to obtain

vector v = 54<cos(69°), sin(69°)>
