What is an internal and External angle

Mathematics
1 answer:
UkoKoshka [18]3 years ago
6 0

Answer:

In geometry, an angle of a polygon is formed by two sides of the polygon that share an endpoint. For a simple (non-self-intersecting) polygon, regardless of whether it is convex or non-convex, this angle is called an interior angle (or internal angle) if a point within the angle is in the interior of the polygon. A polygon has exactly one internal angle per vertex. If every internal angle of a simple polygon is less than 180°, the polygon is called convex. In contrast, an exterior angle (or external angle) is an angle formed by one side of a simple polygon and a line extended from an adjacent side.

Which expression is equivalent to (7 + 2i)(-3 - 4i)?
malfutka [58]
B -13 -34i

(7 + 2i)(-3 - 4i)
Take the 7 then times it buy the second bracket 7x(-3-4i) then take 2i from the first bracket and times it with the second bracket 2ix (-3-4i)

Then keep simplifying

For the given angle 0, identify the reference angle, _
ankoles [38]

Answer:

π\6

Step-by-step explanation:

The reference angle is the smallest angle measured from the terminal side of the angle (where the angle ends) to the x axis. The reference angle is an acute angle (i.e less than 90° or π/2)

For O = 11π/6 = 1.833π

1.833π is in the fourth quadrant between 3π/2 radians and 2π radians. Since it is in the fourth quadrant, the reference angle is given as:

reference angle = 2π - 11π/6 = π\6

Nine fourths minus two thirds
Yuki888 [10]

Answer:

1 \frac{7}{12}  \: or \: 1.583

Step-by-step explanation:

nine fourths is also

\frac{9}{4}

two thirds is also

\frac{2}{3}

subtract,

\frac{9}{4}  -  \frac{2}{3}

L.C.M = 12

\frac{27 - 8}{12}

\frac{19}{12}

1  \frac{7}{12}  \: or \: 1.583
