Answer:
(1- cose0)(1 + cose0) = 0
(1-sin0)(1+sin0) = 1
Step-by-step explanation:
(1- cose0)(1 + cose0) = 0
1st Simplify: \left(1-cos(0))(1+cos(0))
2nd Use the following trivial identity: (0\right)=1
=(1-1)(1+1)
3rd Simplify:(1- cose0)(1 + cose0) = 0
___________________________________________________
(1-sin0)(1+sin0) = 1
1st Use the following trivial identity: sin(0)=0
(1 - 0) (1 + 0)
2nd Simplify: (1-sin0)(1+sin0) = 1
Answer:
The unknown number is 34.
Step-by-step explanation:
x+5=39
x=39-5
x=34
The 2nd part:
( -2,-1)
(0,3)
( -4,2)
The answer is B your welcome
so that makes c 28
