Answer:
72.4 and 107.6
Step-by-step explanation:
on delta math
Answer:
a=2, b=2, c=-12
Step-by-step explanation:
Since it's in factor form, you would first distribute using foil to get 
and then combine like terms when necessary. In this case, the fully simplified version is 
. Therefore your a is 2, b is 2, and c is -12.
The answers are complex numbers...
Here's why...
---------
p+q=18
pq=82
---------
Therefore:
p=18-q
p=82/q
------------
Therefore:
18-q=82/q
q(18-q)=q(82/q)
18q-q²=82
(-1)(18q-q²)=82(-1)
q²-18q=-82
(q-9)²-9²=-82
(q-9)²-81=-82
(q-9)²=-82+81
(q-9)²=-1
q-9=-√(-1)=-i
q-9=√(-1)=i
-----------
Therefore:
q=9-i
q=9+i
-------------
ANSWERS:
When q=9-i, p=9+i
When q=9+i, p=9-i
-----------
Proof:
p+(9-i)=18
p+9-i=18
p=18-9+i
p=9+i
....
p+(9+i)=18
p+9+i=18
p=18-9-i
p=9-i
--------------
More proofs:
p=82/(9+i)
p=(82/(9+i))*((9-i)/(9-i))
p=(82(9-i))/(81-9i+9i-i²)
p=(82(9-i))/(81-(-1))
p=(82(9-i))/82
p=9-i
---------------
p=82/(9-i)
p=(82/(9-i))*((9+i)/(9+i))
p=(82(9+i))/(81+9i-9i-i²)
p=(82(9+i))/(81-(-1))
p=(82(9+i))/82
p=9+i
Answer:
I = Prt
Step-by-step explanation:
Law od sines :
b / SenB = c / SenC
25 / Sen40 = 26 / SenC
25.SenC/Sen40 = 26
25.SenC = 26.Sen40
SenC = 26.Sen40 / 25
SenC = 0,668499114
Applying ArcSen on both the sides:
We have:
ArcSen(SenC) = ArcSen(0,668499114)
C = 41,95°
