Step-by-step explanation:
since we are required to find side |BC| and the value of side |AB| is given as 6.3 cm
hence we find the cosine of the given angle...
cos71 = adjacent ÷ hypotenuse
cos71 = |AB| ÷ |BC|
cos 71 = 6.3 ÷ |BC|
|BC| = 6.3 ÷ 0.325
|BC| = 19.4 cm
To help you understand this, it is helpful to create a sample set of data:
__,__,__,(Q1 is here)__,__,__,(median is here)__, __,__,(Q3is here)__,__,__
A. The first 3 lines are 3 pieces of data in the first quartile.
B. here are 6 pieces of data between the 1st and 3rd quartiles.
D. There are 3 pieces of data in the upper quartile.
(2,5) , (6,8)
Distance formula :
d = √(x₂-x₁)² + (y₂-y₁)²
Simply plug in the values.
d = √(6 - 2)² + (8 - 5)²
Simplify.
d = √(4)² + (3)²
Simplify.
d = √16 + 9
Simplify.
d = √25
So, the distance is 5
