Answer:
θ = -33.69°
Step-by-step explanation:
For Φ>0 and Φ<0 (in general Φ≠nπ where n is an integer), sin(Φ) ≠ 0
Dividing both equations:

Therefore:
arctan(θ) = -2/3
θ = -33.69°
The answer does not depend on the sign of Φ, in fact we just need that the sine does not become zero, which occurs when Φ is equal to an integer times π (radians) or 180 (degrees)
Have a nice day!
Answer:
<h2>7,938 Is the Area, do you need the perimiter?</h2>
Step-by-step explanation:
Answer is D) 2/3 because you divide the whole equation by 3 scene as 2cups=3gal. In order to get one gal, you need to divide the right side by 3 to make one and what you do to one side of an equation, you must do to the other.
Answer:
<em>~ 0.375 centimeters of the snowflake in real life ~</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. Given the information, let us create a proportionality as such:</em>
48 = 1 ⇒ x - centimeters of the snowflake in real life
18 x
<em>2. Now let us cross multiply, and solve through simple algebra for x:</em>
48 * x = 18,
x =<em> 0.375 centimeters of the snowflake in real ife</em>
Answer:
Step-by-step explanation:
use the distance formula to find the lengths of all the sides of the triangle, if all of the sides are the same, its an equilateral. If the sides are different in this case it is a right. You can check this by using the Pythagorean theorem. the distance formula is the square root of (x2-x1)^2+(y2-y1)^2
for the coordinates make sure that you don't mix them up, if you pair the wrong coordinates up, it won't work
(x1,y1) (x2,y2)
