Answer:
tanx = sinx/cosx
Step-by-step explanation:
Given the expression
sin x cos x tan x = 1 - cos^2x
According to trigonometry identity
tan x = sinx/cosx
Substitute into the expression. From LHS
sin x cos x tan x
= sin x cos x (sinx/cosx)
= sin²x
Also since sin²x+cos²x = 1
Hence sin²x = 1 - cos²x (RHS)
The correct option is therefore tanx = sinx/cosx
The answer is 45. The red line and angle says that it is 90 degrees and it cute right through a perpendicular line. And 90 divided by two is 45 so 45 is the answer
Your answer should be 60%, but I'm not sure.

60 miles because if you plug it in, it says she uses 2 gallons of gas. You can substitutes D=30(2), which comes out to 60
No because for example (4-2)(x) is not the same as (2-4)(x). It would be negative
