Mathematics
1 answer:
Pie3 years ago
5 0

Answer:

x =  -1

Step-by-step explanation:

The first step is get rid of the numbers outside this (). So we will get

20+8x=9x+21 (multiplication) And we can get rid of one side of x by subtract 8x on both sides, an then we will get 20= x+21

And we can move the numbers to one side by subtract 21 on each side, and we will get -1=x

And rewrite it:

x = -1

That's the answer.

What else would need to be congruent to show that ABC=DEF by SAS?
KonstantinChe [14]

Answer:

A

Step-by-step explanation:

SAS = side-angle-side

This means that, in order to prove that the triangles are congruent, they must have two congruent sides with the angle between them to the same.

We know that sides AB, ED, AC, and DF are all congruent as they all have a single mark through them. From this, you can conclude that the triangles already share two sides. All we need now is the angles in between to be congruent. This means that angle A and angle D need to be congruent.

I hope this helps!
