< 3 is supplement of < 4, and m< 3=57 find m< 4

m<4 = 123

Step-by-step explanation:

find thing you need to understand is what is supplementary angles.

if the sum of two angles is 180 degree than it is said to be supplementary.

so

m<3 + m<4 =180

57 + m<4 = 180

m<4 = 180 - 57

m<4 = 123

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
