Answer:
The answer to your question is csc Ф = 
Step-by-step explanation:
Process
1.- Determine the sign
We must determine csc Ф in the forth quadrangle, here csc is negative.
2.- Determine the hypotenuse
c² = a² + b²
c² = 3² + (-4)²
c² = 9 + 16
c² = 25
c = 5
3.- Determine csc Ф
csc Ф = 
csc Ф = 
=
Answer:
A. y=2
x+y=2.5
b. x=2 or 5
y=2 or 5
I don't know which on equals 2 and which equals 5, but 5 and 2 are the answers
Step-by-step explanation:
a. 2x0.5=1
b. 2+5=7 and 2x5=10
We know the distance formula is
9)
Here A( -4,2) and B(1,4)
So length of AB
= 
Also C(2,1)
Length of BC
= 
So we can see that length of AB is not equal to length of BC
11.
Now AB = 
Also C(2,-1) & D(4,4)
Length of CD
= 
Yes AB = CD
Answer:
2+i times the square root of 7
27+a=32
a=32-27
a=5
Hope this helped you :)
