Well let's remember csc = hypotenuse/opposite
Let's use the distance formula to find the length of the hypotenuse.
√(0−−8)^
2

(−6−0)^

√
(0+8)^

(−6+0)^
2
√
(8)^

+
(−6)^
2
√
64+36
√
100
H = 10
so csc = 10/opposite
Now to find the opposite length using distance formula
√(0−−8)^2+(0−0)^2
√(0+8)^2+(0+0)^2
√(8)^2+(0)^2
√64+0
√64
O = 8
So csc = 10/8 or 1.25
