Hello :
sin<span>θ = 15/17
</span> use pythagorean identity : cos²θ +sin² θ = 1
cos²θ = 1 - sin² θ
cos²θ = 1-(15/17)²
cos²θ = 1- 225/289
cos²θ = 64/289
cos²θ = (8/17)²
cosθ = 8/17 or -8/17
The answer is: A
A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144°

Answer:
(4x + 2) x 3
4x + 2 x 3
4x + 6
4x/4 = X + 6/4 = 1.5
X = 1.5 I think
P.S. hope this helped if it is correct may I get Brainliest
