The <em><u>correct answer</u></em> is:
AAS
Explanation:
AAS stands for "angle-angle-side." This states that if two angles and a non-included side of one triangle are congruent to the corresponding two angles and non-included side of another triangle, then the triangles are congruent.
In these triangles, we have ∠CAB ≅ ∠CDB given to us to begin with. Throughout the proof, we find that ∠ABC ≅ ∠DCB. We also have that CB is congruent to itself. This is two angles and a side not included, so this is AAS.
Any value of y, except when y = -4.9, will make the expression equal to 2.45.
Answer:

Step-by-step explanation:

Answer:
f(x)=2x-10 ______(given)
f(x)=8 _______(given)
Therefore, according to the above problem
2x-10=8
2x=10+8
2x=18
x=18/2
<u>x=9</u>
<h3><u>9</u> is the right answer.</h3>
