SRT = 20 => STR = 20.
Since STR and STU are supplementary angles, STU = 180 - STR = 180 - 20 = 160, means x = 40.

Answer:
17, 18
Step-by-step explanation:
closest perfect square that is lower than 307 is 289
closest perfect square that is greater than 307 is 324


CosΘ < 0 ->2nd or 3rd quadrant
cotΘ > 0 -> 1/tanΘ > 0 -> tanΘ >0 -> 1st and 3rd quadrant.
So Θ lines in the 3rd quadrant
