Step-by-step explanation:
In the second step there should be (1 - cot x) instead of (1 + cot x)
(1 + tan x) [1 + cot(-x)]
= (1 + tan x) (1 - cot x)
= 1 - cot x + tan x - tan x cot x
= 1 - cot x + tan x - 1
= tan x - cot x
Answer:
$0.07
Step-by-step explanation:
nails = 3.10/155 = 0.02/piece
screws = 7.65/85 = 0.09/piece
0.09 - 0.02 = 0.07
Negative angles are measured clockwise from 0 degrees.
620 = 360 + 260
260 clockwise = 100 degrees anticlockwise
co terminal angle is 100 degrres
