Answer:
29 degrees
Step-by-step explanation:
angle ABD = (x + 9) degrees
angle DBC = (2x - 19) degrees
angle ABC = angle ABD + angle DBC
50 = (x + 9) + (2x - 19)
= 3x - 10
3x = 50 + 10
x = 60/3
x = 20
Substitute x = 20 into angle ABD = (x + 9)
angle ABD = 20 + 9
angle ABD = 29 degrees
![\sqrt{144}](https://tex.z-dn.net/?f=%20%5Csqrt%7B144%7D%20)
is 12. so 12 is the length and width of the square.
To find the circumference: 12(diameter) * constant pi (3.14) = 37.68
37.68 is rounded to 37.7
the circumference of the circle is 37.7 m
Both speeds (quarter horse's and snail's) are already in mph. This means that to be able to determine how many times is the quarter horse faster than a snail, we just have to divide the quarter horse's speed by the speed of the snail.
r = 53.16 / 0.02 = 2658
Therefore, the quarter horse is 2658 times faster than the snail.
Diameter is 18
radius is half of diameter so 9
area is radius*pi ^2 which is 88.83
circumference is diameter * pi so 18*pi = 56.55
The answer to the equation is y=0.5x+5
