Eric is hanging a rectangle mirror that has a diagonal of 47 inches with an angle of depression of 60°. How many square inches is the mirror? (round to nearest tenth)

A) 956.5 in2

B) 1,104.5 in2

C) 1,365.5 in2

D) 1795.5 in2

A) 956.5 in2

Explanation:

First, take a look a the picture I attached you... As you can see, using the information provided by the problem, we can deduce two values, the value of the B angle and the value of the C angle. B is 90 because is a right angle, and C is 30 because the sum of the interior angles of a triangle is equal to 180, so:

90+60+C=180

Solving for C:

C=180-90-60=30.

Now, we need to use this information in order to find a and c which are the height and the base respectively. There a couple of ways to solve this. I will use Law of Sines:

Let's find c:

Let's find a:

Now, the area of a rectangle is the product between its base and its height:

answer: all : )

explanation:

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
