Answer:
x = 100
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
52 + 28 + x = 180
80 + x = 180 ( subtract 80 from both sides )
x = 100

Answer:
The exact Value: x=0
The function operation: 4<em>xsquared</em> = x = x =
2 x = x =
Step-By-Step:
The number of pairs of shoes each man can repair is its velocity time the time.
Call x the repair velocity of the assistant. Then, the repair velocity of the repairman is 2x.
So, the number of pairs of shoes that the assitant can repair in an 8 hour day is: x*8 = 8x
And the number of pairs of shoes that the repairman can fix in an 8 hour day is: 2x* 8 = 16x
As per the statement, 16x + 8x = 16
=> 24x = 16 => x = 16/24 = 2/3 of shoes in 8 hours.
That is the speed of the assistant, while the speed of the repairman is twice that = 4/3 in 8 hours.
So, divide 8 by 4/3 to determine the time to repair one shoe:
8 / ( 4/3) = 3 * 8 / 4 = 3 *2 = 6. That, is the repairman will take 6 hours to repair a pair of shoes.
