Use the Hinge Theorem or its converse and properties of triangles to write and solve an inequality to describe the restriction o
d1i1m1o1n [39]

Answer:

The inequality is: 3x+2

The result is: x>1


Step-by-step explanation:

1. According to the Hinge Theorem, when you have two triangles and two sides of both triangles are congruent, and the included angle of the first triangle is larger than the included angle of the other triangle, the third side of the first one is longer than the third side of the second one.

2. Keeping this on mind, as you can see in the figure, both triangles has two equal sides, and the included angle of the first one is larger than the angle of the second one:

 38°>30°

3. Therefore, the third side of the  first one is longer than the third side of the second triangle. So, you have the following inequality:

3x+2

4. Solve for x. Therefore, you obtain:

2+7

I need to find X, but can't seem to figure it out.
aalyn [17]
The inside of a trapizoid is always 360 degrees. SO 110+ 130 + x + x-3 = 360

240 + 2x - 3 = 360                  236 + 2x = 360              2x = 124       x = 62. I'll leave  what the other angle is to you but that is the answer. Hope that helps. if you don't get the steps i took just ask!

Factor 60x−84 using the gcf
White raven [17]
The greatest common factor of the expressions 60x and 84 is 12 because it can divide both 60 and 84 giving us the answer of 5 and 7, respectively. Factoring out 12 from the terms of the given expression will give us the answer of,
                                60x - 84 = 12(5x - 7)
