First, we need to get the variable by it self.
-2x+6=20
-6=-6
-2x=14
Next, since the operation is multiplication, we need to divided both sides by -2.
X=-7
Here. I hope you can see it.
So there is a possibility I read it wrong, or you typed it wrong. but from what I see, there are NO right triangles.
Step-by-step explanation:
a right triangle has a 90 degree angle. none of these have one.
Answer:
0.4 as a percent is 40%
Step-by-step explanation:
Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
The Hypotenuse-Leg theorem states that two <em>right</em> triangles are <em>congruent</em> if and only if their hypotenuses and any of their <em>corresponding</em> legs are <em>congruent</em>. That is to say:
, 

, 
If we know that
,
,
and
, then we have the following outcomes:


Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
