Question

Find the exact values of sin A and cos A. Write fractions in lowest terms.
A right triangle ABC is shown. Leg AC has length 6, leg BC has length 8, and hypotenuse AB has length 10.

Answer 1

sin A = 8 / 10
cos A = 6 / 10

Answer 2

Simplify

Answer 3

this is how it looks and its a right angle

Answer 4

so 4/5 and 3/5?

Answer 5

yup.

Answer 6

thank you!! :)

Answer 7

Pleasure

Answer 8

would you mind helping me with one more?

Answer 9

No problem

Answer 10

Solve for x. Round your answer to two decimal places. Show your work for full credit.
A right triangle is shown with the hypotenuse labeled x. One angle has a measure of thirty two degrees, and the opposite leg has a length of twenty.

Answer 11

and its a right angle

Answer 12

You can do this yourself with what you learnt from the first problem :).

Write out the equation and solve for x. You will need a calculator to solve it.

Answer 13

wait whats the equation? its pretty easy but i cant remember it :(

Answer 14

sin x = opposite side / hypotenuse.

Answer 15

Sin A in this case.
