Answer:
I think D is right, because usually congruent angles have the same angle measure, and there's no answer choice for 1 and 3.
Answer: 57 = y
Step-by-step explanation: To find the value of <em>y</em> 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.
Answer: It would be the fourth option, $4.84
Step-by-step explanation: To find the new price, multiply 115% to 2.25. 115% is the same as 1.15 and multiply that to $2.25. You would get 2.5875. Now that's the percent in increase so add this to the original price of the gallon of milk which was 2.25. You should get 4.8375, which would round to $4.84.
