Answer:
see explanation
Step-by-step explanation:
To find cscθ we require to find the third side of the triangle.
let 3rd side be x and using Pythagoras' identity
x² + 8² = 9²
x² + 64 = 81 ( subtract 64 from both sides )
x² = 17 ( take square root of both sides )
x = 
Then
cosθ = 
= 
cscθ = 
= 
tanθ = 
= 
Simply view this formula as an equation and solve for R
This would look like:
V=IR
V/I=R/I
V/I=R
ANSWER
R=v divided by I
G(f(x))=? g(x)=2x^2-4? hope this is what you mean
g(f(x))=2(4x+2)^2-4
g(f(x))=2(16x^2+16x+4)-4
g(f(x))=32x^2+32x+8-4
g(f(x))=32x^2+32x+4
Are a and b two points on a line
If they are you can use the distance formula
