Answer:
The first one would be corresponding angles postulate and the second one is linear pair postulate.
Step-by-step explanation:
For all triangles, the angle sum is 180°, therfore we can add all the angles up to solve x
54 + 55 + x + 74 =180
183 + x =180
X = 180 - 183
X = - 3 °
Don't worry, negative result is normal and possible.
7.1 degrees.
5.7-(-1.4)
5.7+1.4= 7.1

Answer: 110 square inches.
Step-by-step explanation:
The volume of a rectangular box would be:

In this case, we know the volume, the length and the height, and we don't know the width, so we're going to isolate it:

Substituting the data:

This width is also the width of the top of the box, so the area of the top would be:
