The answer for your problem is
Answer:
true
Step-by-step explanation:
all the sides match up. One side (the base) is shared which means they are the same length. The triangle at the top has a single hash on a side and so does the bottom one. This means they are the same length. The same thing occurs with the last remaining sides, they are congruent because they both have two hash lines. Since all three sides of both triangle add up, the triangles ARE CONGRUENT.

$25! Think about it, to get $15.90 as your discounted price, the unknown number must be multiplied by 60% to get $15.90. If you wanna find the original price, do the opposite! What is $15.90 divided by .6? $25!
Answer:
EF is 16.
Step-by-step explanation:
So we know that Point E is somewhere on Line DF. In other words, DE plus EF must equal DF. In an equation, this is:

We are given that DE is 2x, EF is 2x-6, and DF is 3x+5. So, substitute:

Now, solve for x.
On the right, combine like terms:

Subtract 4x from both sides:

Subtract 5 from both sides:

Divide both sides by -1:

Now that we know x is 11, substitute this back into the equation for EF to find EF.

Substitute 11 for x:

Multiply:

Subtract:

And we're done!
