I found the answer key t your worksheet. If you need an explanatin ask in comments and I will get back ASAP.
An isosceles triangle is one in which 2 angles have similar
measure while the other one is different. In this case, the 2 vertex angles
have a measure of 42 degrees, therefore the third angle which is equal to (2x +
3) is:
(2x + 3) + 42 + 42 = 180
2x + 3 = 96
<span>x = 46.5°</span>
Andrea can cut 4 1/2 (or 4.5) inch pieces from her original piece.
18/4 = 4.5
Hope this helps!
