Question

1. What is the value of sin 67° to the nearest ten-thousandth?

2. What is the value of cos 34° to the nearest ten-thousandth?

3. 4√6/√30 simplify by rationalizing the denominator.

Answer 1

i dont know the other answer but i know that sin 67 is 0.9205

Answer 2

Using a calculator, the values to the nearest 10 thousands are

1)
`\sin 67^o=0.9205`

2)
`\cos 34^o=0.8290`

3) The given fraction is
`(4√(6))/(√(30))`. Rationalizing the denominator,
