Answer:

angle A: 87°

Step-by-step explanation:

Both the sides: A and C are same to each other. let the angle be x

Find the total interior angle of a polygon with 4 sides:

(n-2)*180

(4-2)*180

360°

when all angles sum up, they equal to 360°

so:

115° + 71° + 2x = 360°

186° + 2x = 360°

2x = 174°

x = 87°

ella [17]

So a circular pool will be in the shape of a cylinder. and the formula for finding the area of a cylinder is $2 \pi r^{2} +2 \pi rh$ . r=radius, h=height. If we put the numbers into the equation it is $2 \pi 14^{2} +2 \pi 14(4).$ .14 squared is 196 and 4*14= 56. So our equation is now $2 \pi (196)+2 \pi (56)$ . 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(196)+6.283(56). Just multiply them. 1231.504+351.858= <span>1583.362</span> is your final answer.
