Answer:
40
Step-by-step explanation:
Angles in a circle add up to 360 degrees.
135 + 145 + x + x = 360
280 + 2x = 360
2x = 80
x = 40
To find the quotient, we can use a calculator. Problem is that we get a decimal, so 52 won't divide evenly. When using a calculator the whole number part is the quotient.
1052 + 52 = 20.2307692....
Now, 52 x 20 = 1040. Since 1052 - 1040 = 12 we can properly report the quotient and its remainder.
So 1052 + 52 = 20 (its quotient) and 12 (its remainder).
Answer:
4 friends, 40$, so each had 10$
40/4=10-7.5= 2.5
Each had $2.50 left
