Answer:
(√6)/2 square units
Step-by-step explanation:
The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.
QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)
QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)
The cross product is the determinant ...
The magnitude of this is ...
|QR × QS| = √((-2)² +1² +(-1)²) = √6
The area of the triangle is half this value:
Area = (1/2)√6 . . . . square units
Answer:
B
Step-by-step explanation:
Probability of getting 9 or 11 = 2 /6 =1/3
Probability of getting tails in coin = 1/ 2
Probability of getting 9 or 11 AND tails in coin toss = 1/2 * 1/3
= 1/6

Answer:
<h3>A) Not enough information or not similar.</h3>
Step-by-step explanation:
We are given a triangle with a segment that connects two points of the two sides of given triangle.
There are different triangle similarity theorems are available there as given in options.
Side Side Side (SSS) triangle similarity theorem.
Side Angle Side (SAS) triangle similarity theorem.
Angle Angle (AA) triangle similarity theorem.
But in the shown figure, we are not provided much information about it's sides and angles.
Therefore, correct option is :
<h3>A) Not enough information or not similar.</h3>
Answer:
The correct answer would be 1/16 or .0625
