Answer:</h3>
A) the angles
<h3>
Step-by-step explanation:</h3>
Similar triangles are triangles that have the same shape but different sizes.
Angles
Since similar triangles have the same shape, all of the angles must be congruent. If any of the angles are different sizes, then the shape of the entire triangle would change.
Sides
The sides of a similar triangle are not necessarily congruent. However, because all of the angles are congruent, the sides are proportionate. This means that if you are given the sides and angles of one triangle, you can find the sides and angles of any similar triangle.
Answer:
a = 36
Step-by-step explanation:
3 + (11/12)a = 36
Subtract 3 from both sides
(11/12)a = 33
multiply both sides by 12
11a = 396
Divide both sides by 11
a = 36

Let's say Diana is "x" years old today.
in 3 years, she's going to be " x + 3 " years old.
33 years ago, she was " x - 33 " old.
how much is 4 times that anyway? well 4(x-33), that's 4 times as 33 years ago her age.
now, we know in 3 years, x+3, she'll be "<span>4 times as old as she was 33 years ago", 4(x-33), therefore, those amounts are equal then,
</span>
<span>
why is it most logical to use "x" for her age today?
well, because 3 years from now is just x + 3
and
33 years ago is x - 33, 4 times that is 4( x - 33 ).
works very well as a point of reference.</span>
