A cricular arena is lit by 5 lights equally spaced around the perimeter of the arena. What is the measure of each angle formed b

Kitty [74]

Answer:

108°

Step-by-step explanation:

Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).

The sum of all interior angles of pentagon can be calculated using following formula

$(n-2)\cdot 180^{\circ},\\ \\(5-2)\cdot 180^{\circ}=3\cdot 180^{\circ}=540^{\circ}$

All interior angles in regular pentagon are of equal measure, so

$\dfrac{540^{\circ}}{5}=108^{\circ}$

Thus, the measure of each angle formed by the lights on the perimeter is 108°.

Miguel deposits 680.00 in an account that pays 3.5% simple interest. if he neither adds more money nor withdraws any money, what

quester [9]

I=PRT
I=interst
P=invested amount
R=rate in decimal
T=time in years

given
P=680
R=3.5%=0.035
T=6

I=680*0.035*6
I=142.8
that is interest

total is interest+principal=680+142.8=822.8

after 6 years, $822.80 is in the account
