I gotchu. This is pretty simple okay? So when the problem is asking for X and X is inside the triangle, all you have to do is add the other two numbers, which are shown, and subtract it by 180 to get X. For example for problem number 1. You have x that’s inside the triangle, so you add up 47 and 58 which equals to 105 and then take that number and subtract it FROM 180. So the whole equation would be 47+58=105 180-105=75 so X=75. Now for other problems it’s the exact same thing all you have to do is take the other numbers add them up subtract it from 180 and you get X
Answer :
F-1(x)=-x/4-7/4
This is right
Go get help to sum sites!!!!!
A= 8.55 X 10/-5 and B= 8.55 x 10/6
The point that can be found on the line y= 2x - 7 is (0,-7)
