Answer:
a = 2x, b = 3.
Step-by-step explanation:
8x^3+27 = (2x)^3 + 3^3
a = 2x and b = 3.
We can cube root 8x^3 getting 2x and cube root 27 getting 3.
Answer:
The correct answer is option <em>B. AA</em>
<em></em>
Step-by-step explanation:
Given two triangle:
and
.
The dimensions given in
are:

We know that the sum of three angles in a triangle is equal to
.

The dimensions given in
are:

We know that the sum of three angles in a triangle is equal to
.

Now, if we compare the angles of the two triangles:

So, by AA postulate (i.e. Angle - Angle) postulate, the two triangles are similar.
by <em>AA theorem.</em>
<em>So, correct answer is option B. AA </em>
20 because 19 16/33 is the exact answer. Since they ask about how much that can be rounded up to 20
