Answer:
x = 8
Step-by-step explanation:
Solve for x in the equation: 5 = x - 3
x - 3 = 5
Isolate x by adding 3 on both sides of the equation.
x - 3 + 3 = 5 + 3 (on left side: +3 and -3 cancel out)
x = 8
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
