By Pythagoras AB^2 = 12^2 - 6^2 = 108
AB = sqrt 108 = 10.39 to nearest hundredth
The perpendicular from M to DC will be parallel and equal to AB so it = 10.39.
Also AB^2 = CB * DB
108 = 6 * DB
DB = 108/6 = 18
so DC = 18-6 = 12
MD^2 = (1/2*12)^2 + 108 = 144
so MD = 12
Answer:
4250 children
Step-by-step explanation:
72-38=34 degrees
34 degrees therefore is 578 people
so, 1 degree is 17 people
There is 360 degrees in a circle so we must subtract the degrees of the men and female segments in order to know how many degrees children takes up:
360-72-38=250
250x17=4250 children
You could use sin(25)=12/H
solve for H.
