Answer to Problem 27CUR

The final answer is greater than 0 and less than 1.

Explanation of Solution

Given information: We have thegivenstatement :The sine of any acute angle must be greater than …. and less than ….

We know that acute angle is an angle whose measure lies between $0^{°}$ and ${90}^{°}$

Now, the value of $\sin 0^{°}=0$ and $\sin {90}^{°}=1$

Therefore, the sine of any acute angle must be greater than 0 and less than 1.
