About 2983 ft as you find the circumfrence and mult by 5
I think you meant to add more to your question (posting the specific problem).
In general, one special right triangle is the <span>45°-45°-90° triangle, in which both legs are congruent and the hypotenuse = √2 * the length of the leg. if you happen to not have the length of the leg, the formula for finding the leg is: leg = hypotenuse / √2
Another special right triangle is the </span><span>30°-60°-90° triangle. With this kind of triangle the length of the hypotenuse is twice the length of the shorter leg. The length of the longer leg is √3 times the length of the shorter leg.
hypotenuse = 2 * shorter leg
longer leg = √3 * shorter leg</span>
Answer:
Step-by-step explanation:
28° into radians
28° = ( 28 * 
)
Divide 28 and 180 by 4 we get
= ( 
)
Hope it helped :)
Half-perimeter=length+width=width+3+width=43, 2×width=40 so width=20cm and length=23cm.
