Answer:
-5
Step-by-step explanation:
11-16=-5
Angle G is common to both of the triangles.
*Hint: The Law of Sines is Sin A/a = Sin B/b = Sin C/c
In order to solve this equation, you will have to use this equation:
A= sin^(-1)[a sinB/b]
A= sin^ (-1) [12 (sin 46°) / 11]
A = sin^ (-1) [8.632077604/11]
A = sin ^(-1) [0.7847343276]
A = 51.69611349
Therefore, Sine A would be about 52°
Identity to verify:
Recall that
Divide both sides by and we get
or
So if we multiply the numerator and denominator of
by , we get
Then as long as , we can cancel terms to end up with
and establish the identity.
The above two way table shows the number of girls and boys who scored below average and above average grades.
We have to find the probability that a randomly selected girl will have above average grades.
Probability is the measure of an likelihood that an event will occur.
Probability is calculated by the formula =
Total number of girls = 38
Number of girls Girls who have above average grades = 22
P(randomly selected girl with above average grades)=
= 0.58
