The 3rd one is the right answer I think
X= 28
explanation: pythagorean theorem
Answer:
see explanation
Step-by-step explanation:
using the trigonometric identities
• sin2x = 2sinxcosx
• cos2x = 2cos²x - 1
• sin²x + cos²x = 1
sinx = ±
= ±
= ±
= ± = ±
since sinΘ > 0 then sinΘ = =
sin2Θ = 2 × × - = -
cos2Θ = 2 × (- )² - 1
= 2 × - 1
= - 1 = =
