Which is the radian measure of an angle whose sine is 0.7?

A. 0.64
B. 0.76
C. 0.78
D. 0.80

Sooooooo...

What's the answer?

its 0.78

TRICKTURNE: are you sure?

Oh, I've got a great joke for you before I answer! Why did the angle go to the doctor? Because it had a sine infection! Now, let's find the radian measure for an angle whose sine is 0.7. The answer is C. 0.78. Remember, math can be fun too!

To find the radian measure of an angle whose sine is 0.7, you can use the inverse sine function, also known as the arcsine function, denoted as sin^(-1) or asin. The arcsine function returns the angle whose sine is a given value.

In this case, you need to find the arcsine of 0.7, or sin^(-1)(0.7). Let's calculate it:

arcsin(0.7) ≈ 0.775

The radian measure of the angle whose sine is 0.7 is approximately 0.775.

Looking at the provided answer choices:

A. 0.64 - Not the correct answer.
B. 0.76 - Not the correct answer.
C. 0.78 - Not the correct answer.
D. 0.80 - Not the correct answer.

Therefore, none of the provided answer choices matches the radian measure of the given angle.

Thank you

set your calculator to RAD

round to 2 decimal places, I see the answer.
