Answer:
87
Step-by-step explanation:
all the angles of a triangle out of 180 so subtract the two numbers you have from 180
1 : 40 = 6 : 240
On the ground the fence would be 240 inches long
240 / 12 = 20 feet long fnce
So before i give u the answer i will explain
step 1- Underline key info( 40PIZZA and 120 PEOPLE)
step 2- do 140\40 which then u will get 3( we do this cause we wanna find out how many times this number can go into 120)
step 3- ur answer is 3 pizza per person
I could be wrong but this is what I think.
D=RT
D=39 (3)
D=117
