Can someone please explain how to do this?

e = 30

Step-by-step explanation:

Since 114 and the adjacent angle are supplementary, that means they add up to 180.

114 + x - 114 = 180 - 114

x = 66

Now, solve inside the triangle which adds up to 180.

54 + 66 + 2e = 180

120 + 2e - 120 = 180 - 120

2e / 2 = 60 / 2

e = 30

 e = 30

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
