The solution to the question is:
c is 6 =
b is 5 =
cosB is 2 =
a is 4 =
cosA is 3 =
cosC is 1 =
<h3>What is cosine rule?</h3>
it is used to relate the three sides of a triangle with the angle facing one of its sides.
The square of the side facing the included angle is equal to the some of the squares of the other sides and the product of twice the other two sides and the cosine of the included angle.
Analysis:
If c is the side facing the included angle C, then
= + -2ab cos C-----------------1
then c =
if b is the side facing the included angle B, then
= + -2accosB-----------------2
b =
from equation 2, make cosB the subject of equation
2ac cosB = + -
cosB =
if a is the side facing the included angle A, then
= + -2bccosA--------------------3
a =
from equation 3, making cosA subject of the equation
2bcosA = + -
cosA =
from equation 1, making cos C the subject
2abcosC = + -
cos C =
In conclusion,
c is 6 =
b is 5 =
cosB is 2 =
a is 4 =
cosA is 3 =
cosC is 1 =

To answer this question you must know that there is a theorem called the "Two secants angle theorem", which establishes that the measure of an angle formed when two secants intersecting outside the circle is equal to 1/2 the difference of the two intercepted arcs.
Therefore, as you can see, the correct answer is the option B): B)<span>1/2 the difference of the intercepted arcs</span>

Answer:
4.8 m
Step-by-step explanation:
The area of a rectangle is the product of length and width. This relation can be used to find any of the dimensions when the other two are known.
__
Here, we know area and length, so we can find width.
A = LW
W = A/L = (29.76 m²)/(6.2 m) = 4.8 m

Answer:
1/2 the jellybeans are yellow... or 25 jellybeans
Step-by-step explanation:
1/5 is the same thing as 2/10.
2/10 + 3/10 = 5/10
5/10 are blue and green and the other 5/10 is yellow.
5/10 can be simplified to 1/2
1/2 of 50 is 25
I hope this helps you!! :)
