Question

How do I set up and solve number 6

Answer 1

Based on the fact that the angle is acute, we know that the expression $6x - 45$ must be between 0 and 90. This is shown as:

$0 < 6x - 45 < 90$

We can now solve this inequality as shown below:

$45 < 6x < 135$

$\dfrac{15}{2} < x < \dfrac{45}{2}$

The inequality would be represented as 15/2 < x < 45/2.
