Answer:
A.) <em>m ∠ ABD = m ∠ CBD</em>
Step-by-step explanation:
The line segment BD was constructed as an angle bisector, which means that ∠ ABC was split directly in half. This means that the two resulting angles are congruent.
Ok can you help me with this 137x8 multiply with expanded form please???? I will help with yours

Complete the square on the left side:

Then the equation becomes

Both 14 + √186 and 14 - √186 are positive numbers, so we can take the logarithm (base 3) of both sides without issue:

Then in increasing order, the solutions are
<em>c</em> = log₃(14 - √186), <em>c</em> = log₃(14 + √186)
If I am correct, it would be C because there are only 2 sides on the coin, so you have a 50/50 chance of heads again or tails
