The answer is 135/1, or 135 as a whole.
if the horizontal lines are all parallel, then yes, as long as the angles are on the same side. If the horizontal lines are parallel but the angles are on opposite sides, then no. If the horizontal lines are not parallel, then it would require more work to figure it out
On your calculator, make sure you're in radian mode, not degree mode, that you are in a trig coordinate plane (do this by hitting "zoom" and choosing ZTrig), and when you enter the function into the "y =", you have to enter it in like this: 7cos(2x)-3. Hit "graph" and you'll see that the wave goes through the x-axis in 4 places within your specified interval. Hit 2nd and "trace" and then "zero". Move your cursor so it's just above the x-axis where the curve goes through and hit enter, then move it so it's just below the x-axis where the curve goes through and hit enter again. Hit enter a 3rd time, and you SHOULD see that your x has a value while y = 0. Do that for all of the places where the curve goes through the x-axis. That's how you find the zeros of a trig curve (or any curve, for that matter) on a calculator. The zeros are the solutions. If this was solvable like a regular equation, using trig identities and right triangles, you wouldn't have to use your calculator. But just like when you go to factor a second degree polynomial and you're having trouble with it you can use the quadratic formula and it's never-fail, neither is your calculator.

Solution,
![5 \frac{3}{4} \div 1 \frac{1}{2}](https://tex.z-dn.net/?f=5%20%5Cfrac%7B3%7D%7B4%7D%20%20%5Cdiv%201%20%5Cfrac%7B1%7D%7B2%7D%20)
Convert the mixed number to an improper fraction
![\frac{23}{4} \div \frac{3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B23%7D%7B4%7D%20%20%5Cdiv%20%20%5Cfrac%7B3%7D%7B2%7D%20)
To divide by a fraction, multiply by the reciprocal of that fraction
![\frac{23}{4} \times \frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B23%7D%7B4%7D%20%20%5Ctimes%20%20%5Cfrac%7B2%7D%7B3%7D%20)
Reduce the numbers with the GCF 2
![\frac{23}{2} \times \frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B23%7D%7B2%7D%20%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B3%7D%20)
Multiply the fraction
![\frac{23}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B23%7D%7B6%7D%20)
