Answer:
to know the summation of angles: (n-2)*180
here (n) represent numbers of sides
12)we have 5 sides (n=5)
(5-2)*180=540
x=540-(105+135+92+87)=121
13)we have 8 sides (n=8)
(8-2)*180=1080
x=1080-(116+158+141+124+136+132+129)=144

Area = pi * r^2
Area = pi * 12^2 = 452.39 square units
Circumference = 2(pi) * r
2 * pi * 12 = 75.40 units
Aimee's karate class starts at 3:45
5:00 - 0:15 = 4:45 - 1:00 = 3:45

Answer:
0.64s
Step-by-step explanation:
Hello!
To solve this problem we must use the equation to determine for what time (t), the ball touches the ground that is when h = 0
Now we have a quadratic equation, which has two answers, for this we use the following equation
a = number that accompanies the variable t ^ 2
=-16
b = number that accompanies the variable t
=4
c = independent number of t=4
solving
remember that when the equation is quadratic it has two answers, one with the sign (+), and another with the sign (-), you choose the positive result since it is impossible for the time to be negative
t1=0.64s
t2=-0.39s
answer=0.64s
