Answer:
9/4
Step-by-step explanation:
see image
2/3 is 2 × 1/3.
We can separate the exponent into 1/3 power raised to the 2nd power. 1/3 power is the same as cube root.
27 and 8 are both perfect cubes. 3^3 and 2^3.
Thats how you go from 27/8 to 3/2.
Then square it.

If you can't figure out how to do it, you can always use your answer choices, so for example, use choice a (21 degrees). Plug in 21 for x for both equations. So for the first equation that would be 7(21)-1= 146 and second equation 3(2)-9= 54. Then you would add the results, 146+54=200. In that case, choice 21 is wrong because both of these angles should equal to 180 since it is a supplementary angle. I hope that helped.
