Answer: OPTION A
Step-by-step explanation:
It is important to remember the "Angle Addition Postulate" in order to solve this exercise.
You have this larger angle:
According to the "Angle Addition Postulate", if the point "C" is in the interior of , then the measure of this angle can be obtained by adding the angle
and the angle
.
You can observe in the figure that:
Then you get that:
Therefore, the correct answer is Option A.
Answer: OPTION C.
Step-by-step explanation:
For this exercise it is important to remember the following:
Knowing this and based on the information provided in the exercise, you can make the conversion from kilograms to ounces. This is:
According to the exercise, Miriam's procedure was:
So you can identify that she made a mistake.
Notice that:
1. Miriaim multiplied correctly.
2. Butt the third fraction should be and not
.
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.
