Answer:
19.1
Step-by-step explanation:
Let's assign some variables to this triangle.
angle A = 63°
angle B = unknown
angle C = 71°
side a = 18
side b = y
side c = x
By the law of sins, applicable to ALL triangles, we have:
Let's then take the equation for angles A and C, in order to isolate the c (which is our x to find).
we then have
So, the answer is the second one.
Answer:
Option D.
Jenn's answer is not correct. She got it substituting 
into the equation and solving for "x".
Step-by-step explanation:
Given the following equation:
Since you need that 
, you hace to substitute that value into the equation:
Now you need to solve for "c":
Therefore for a a value of 
, you get
Then, the you can identify that the correct answer is the one given in the Option D.
Jenn made a mistake, because she substituted into the equation and then solve for "x":
Answer:
t/16
•The correct algebraic expression is StartFraction t Over 16 EndFraction
Step-by-step explanation:
Quotient of a number and 16
Let the number=t
Quotient represent division
The expression can be written as t/16
•Replace "a number" with a variable, like t.
•Quotient represents division.
•The correct algebraic expression is StartFraction t Over 16 EndFraction
119200/100000
move the decimal place to the left 5 times.
1.192 =
It is much closer to 1
Answer:
Step-by-step explanation:
From the given information.
An ordinal scale measurement does not give room to know the actual difference that coexists between the two measurements in a variable but in an interval scale of measurement, it is possible to deduce the actual difference that coexists between the two measurements in a variable.
Similarly, the ordinal scale only shows the rank of observations as per size and magnitude but in case of interval scale, it consists of classes with equal size, differentiated into direction and magnitude.
