Step-by-step explanation:
The hypotenuse is always the side that is across from the corner. In this triangle, the hypotenuse is 14.
Answer:
a) r(t) = 0.783t radians
b) h(t) = 30cos(0.783*t) feet
Step-by-step explanation:
The situation is depicted in the picture attached
<h3>(see picture)
</h3>
Since the angular speed is constant, to find an expression for the angle r(t) in radians we just cross-multiply using the fact that 1 min = 60 seconds
4.7 radians __________ 60 seconds
r(t) radians ____________ t seconds
The height h(t) after t seconds is given by
h(t) = 30cos(r(t)) ===>
h(t) = 30cos(0.783*t) feet
Number of sides is 6- Hexagon
Sum of interior angles equation- s=(n-2)*180
s= (6-2)*180
s= 4*180
s=720
Sum is 720
