Answer:
48.983.
Step-by-step explanation:
(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).
Using order of operations (PEMDAS):
20.003 + [(30.1 + 5.75) - 6.87] Work out the inner parentheses first:
= 20.003 + [35.85 - 6.87] Now the outer parentheses:
= 20.003 + 28.98
= 48.983.
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 =
