What is the value of Y?

57 = y

Step-by-step explanation: To find the value of y in this problem, we use the exterior angle theorem which states that the measure of the exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

So in the diagram shown, the exterior angle, 114,

is equal to the sum of the remote interior angles, y + y.

So we have 114 = y + y.

Solving from here, first combine like terms on the right side.

So we have 114 = 2y.

Now divide both sides by 2 to get 57 = y.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

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.
