35+25=60
y=60
If you add the opposite side values of the triangle (not the one touching the y), you get the value of y). 35+25=y
This works because y+x= 180 and the three angles of a triangle add to 180.
Carlos is wrong since when subtracted 2175 from 1833 you get 342 so that's about one third of what he said.
7.32a + 2.1(2.7 -18a)
7.32a + 5.67 - 37.8a (multiply 2.1 to 2.7 and 18a)
5.67 - 30.48a (combine 7.32a and -37.8a since they are like terms)
It is a conversion factor.
For example to convert from eett to inches you multiply by 12 in/ft, which is the conversion factor.
