<span>Tan(2x) ‒ 1/Tan(2x) = 0 \\ clear the denominators by multiplying both sides by Tan(2x) </span>
<span>Tan²(2x) ‒ 1 = 0 as long as Tan(2x) exists and ≠ 0 </span>
<span>Tan²(2x) = 1 so Tan(2x) = -1 or Tan(2x) = 1 </span>
<span>Therefore, 2x = 45° or x = 22.5° or 2x = -45° or x = -22.5° </span>
<span>There are many other values of x that work but not between -180° and 180°. </span>
Answer:
24 picture frames
Step-by-step explanation:
Since a student takes 1/6 hour to paint a picture frame, so in an hour, the student will paint a total of 6 picture frames. So to find the number of picture frames in 4 hours, you just need to multiply 4*6 to get 24 picture frames.
Answer:144
Step-by-step explanation: a coin has 2 possibilities so 2 coins have 2x2 = 4 possibilities. A normal six-sided dice has 6x6 = 36 possibilities. 4 x 36 = 144 (this might be wrong)
