Answer:
.
Step-by-step explanation:
We want to find the value of .
Note that;
This implies that;
Also 270 degrees is a quadrantal angle.
On the unit circle, is the x-coordinate of the point
Hence, .
The apothem of a square is equal to half its side length. Therefore, the square has a side length of 5. The area of a square equals the s^2. Therefore, the area of the square is 5^2=25. (B)
Answer:
2/3
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
= ( -10 - -6)/( -9 - -3)
= ( -10 +6)/( -9 +3)
= -4/-6
= 2/3
Answer:
Side = 12 cm, side = 5 cm, side = 8 cm
Step-by-step explanation:
In order to form a triangle with non-zero area, the sum of the shortest two sides must exceed the longest side.
This will be the case for {5, 8, 12}, but not for any of the others.
___
The side lengths {5, 8, 13} will form <em>a triangle with zero area</em>. This is acceptable according to one version of the triangle inequality (a+b≥c) but not according to the other version (a+b>c). Since you are apparently expected to find one "right answer", we assume the answer you want is the one shown above.
