The formating is a bit confusing but I think the answer to your question would be, "Matt's error is that he just divided the denominator and not the numerator "
Answer:
The 13.2 meters from that point on the ocean floor to the wreck.
Step-by-step explanation:
As given
A ship's sonar finds that the angle of depression to a ship wrack on the bottom of the ocean is 12.5°.
If a point on the ocean floor is 60 meters.
Now by using the trigonometric identity.

As shown in the figure given below.
Perpendicular = CB
Base = AC = 60 meters

Put in the identity





CB = 60 × 0.22
CB = 13.2 meters
Therefore the 13.2 meters from that point on the ocean floor to the wreck.
4 rows and 875 columns, or 875 rows and 4 columns
Answer:
We need to find which expressions are equivalent to
,
or neither.
: We extract the greatest common factor which is 6. Remember, when we extract a GCM, we divide each term by it.

Therefore, this expression is equivalent to neither of the given expressions.
: We just need to apply the distributive property.

Therefore, this expression is equivalen to
.
We use the same process to the other expressions.



, equivalent to neither.
The answer is b the rounded to 2 decimal places
