Answer:
The answer is below
Step-by-step explanation:
Select the quadrant in which the terminal side of the angle falls.
210° terminates in quadrant
-150° terminates in quadrant
390° terminates in quadrant
Solution:
The x and y axis divides the cartesian plane into four equal parts known as the four quadrants.
Angles between 0° and 90° are in the first quadrant, angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant while angles between 270° and 360° are in the fourth quadrant.
a) Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
b) -150° = 360 - 150 = 210°. Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
c) 390° = 390° - 360° = 30°.
Since 30 degrees is between 0° and 90°, hence it terminates in the first quadrant.
The equation to find the Volume of something is length*Width*height
therefore:
(I'm confused as to what <span>10/1/2 means so)
</span>
•on the assumption that 10/1/2 means 10 and a half - 10.5
then it would be - 15*10.5*2.5 = 393.75m^3
<span>•on the assumption that 10/1/2 means 10 divided by 1/2 then it would be:
</span>15*20*4 = 1200m^3
Divide 72 by 129 , then multiply the decimal by 100:
72 / 129 = 0.55813
0.55813 x 100 = 55.813% (Round the answer as needed).
The two quadrilateral with the listed properties are kite and rhombus respectively.
<h3>Properties of a kite</h3>
- It has two diagonals intersecting at right angles
- A kite is symmetrical about its main diagonal
- Angles opposite to the main diagonal are equal
- The kite can be viewed as a pair of congruent triangles with a common base
- Its diagonals are perpendicular
<h3>Properties of a rhombus</h3>
- All sides of the rhombus are equal
- The opposite sides are parallel
- Opposite angles are equal
- Diagonals bisect each other at right angles
- Diagonals bisect the angles
- The sum of two adjacent angles is equal to 180 degrees, that is, are supplementary
Thus, the two quadrilateral with the listed properties are kite and rhombus respectively.
