Step 2 contains the mistake made.
3x + 18 = 2x + 8
Next, subtract 2x from both sides.
x + 18 = 8
The correct choice is D) 16. This is because 16 = 2*2*2*2 has solely 2 as its prime factor. Whenever the prime factors of the denominator are either 2 or 5, the decimal will be terminating. Examples of this include fractions such as 1/2, 1/5, 1/10.
Answer: The initial two triangles can be confirmed as congruent via the SAS criterion.
Step-by-step explanation:
The SAS postulate states that if two sides and the angle they enclose in one triangle are equal to two sides and the angle of another triangle, then those triangles are congruent.
The first pair meets this criterion as the included angle matches the two sides and the angle from the second triangle, which leads to their congruence by SAS.
In the next illustration, the two triangles are congruent according to the ASA postulate, not SAS.
In the third diagram, there is no congruence between the triangles through any postulate or theorem [due to the absence of SSA].
The last diagram displays congruence under the SSS postulate, not SAS.
