Answer:
x = 21
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
Combine like terms. (x + 3x) and (-4 + 100)
x - 4 + 3x + 100 = 180
Subtract 96 on both sides.
4x + 96 = 180
-96 -96
Divide 4 on both sides.
4x = 84
--- -----
4 4
And you get a solution of 21.
x = 21
<u>Check:</u>
Substitute 21 into x.
Add/Subtract from left to right.
21 - 4 + 3(21) + 100 = 180
17 + 63 + 100 = 180
80 + 100 = 180
180 = 180

Step-by-step explanation:
Answer:
see the explanation
Step-by-step explanation:
we know that
If two figures are congruent, then the corresponding sides and the corresponding angles are congruent
In this problem, the corresponding sides are congruent, but the corresponding angles are not congruent
therefore
The square ABCD and the rhombus GHIJ are not congruent
