Answer: where is the quadrilateral
Step-by-step explanation:
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
It is 109
Hope it helps !!
Using the formula
L=rx (x=angle)
x=L/r
x=8/3
x=2.6 radians
