Answer:
They are congruent, they are right angles
Step-by-step explanation:
Just in general, all vertical angles are congruent.
But in this situation, perpendicular lines will always create right angles.
Answer:
2500
Step-by-step explanation:
Let the first square number be
then the next square number is
.
The difference between these two consecutive numbers is 99.
This implies that:

We expand to get:

Simplify:


Divide both sides by 2

Therefore the value of the larger perfect number is
.
we'd do the same as before on this one as well.
if we take 27.99 to be the 100%, what is 12 off of it in percentage?

It’s probably A. (1,2) hope this helps..
Answer:
A is correct < C and < C" are congruent after both the translation and the dilation.
Step-by-step explanation:
The shape of the triangle remains the same after the translation and the dilation. After the dilation the new triangle is bigger by a factor 2 but the shape ( and therefore the angles are equal. The 2 triangles are similar,
