Answer:
2/3 : 4/5 or 0.67 : 0.8
Step-by-step explanation:
it's already in its lowest form.
Well the angles should all equal 360. Since you know 90 and 160 then 360-90-160=110. Angle 2 is 90* so 110-90=20 so angle 4 is 20. Angle 2+ angle 4: 90+20=110 or C :)
The answer would be 119 and 4/7
THIS answer is A. It is equilateral but not equiangular. Hope this helps!

Aye Sir!
The length of the side = <span>The length of the arc intercepted by the central
<span>angle
</span></span>∴ length = Θ r
where Θ = <span>central<span> angle in radians
and r = radius
∴ </span></span><span>Θ = 70° = 70 * π /180
</span><span>r = 13 in.
∴ </span>length = <span>(70 * π /180) * 13 ≈ 15.88 in.
