Answer:
x = 3
Step-by-step explanation:
9x + 8 = 4x + 23
9x - 4x + 8 = 4x - 4x + 23
5x + 8 = 23
5x = 23 - 8
5x = 15
5x/5 = 15/5
x = 3

So these are trig questions so for question 1 you have the opposite side and you are trying to find the adjacent side so you use tan = o/a . So therefore tan(67) = 17/a so 17/tan(67) is a so a is 7.216 which is 7.2 to the nearest tenth.
For question 2 you have the adjacent side and are trying to find the opposite side so you do tan(24) is x/12 so tan(24) x 12 is x so x is 5.34 or 5.3 to the nearest tenth.
Question three you have the adjacent and are trying to find the opposite so you do tan(72) = x/20 so you do tan(72) x 20 to get 61.55 or 61.6 to the nearest tenth.
Hope this helps :)
