First one. PNO =22 MNO =40
Step-by-step explanation:
(2 cos(2x)) / (cot x – tan x)
Multiply top and bottom by sin x cos x:
(2 cos(2x) sin x cos x) / (cos² x – sin² x)
Use double angle formula:
(2 cos(2x) sin x cos x) / (cos(2x))
2 sin x cos x
Use double angle formula:
sin(2x)
Plug 1 in for x to get 7y=3(1)-7
7y=-4
y=-4/7
Answer:
14/7=2
14 over 7 equals 2 so 2=2.
