Step-by-step explanation:
log x = 1 + a
a = log x - 1
log y = 1 - a
a = 1 - log y
So
log x - 1 = 1 - log y
log x + log y = 2
log (xy) = 2
xy = 100
Answer:
12x-30 is the answer simplified
Step-by-step explanation
theres no much of a process
Answer:
x = 240°, x = 300°
Step-by-step explanation:
Using the identity
sin x =
=
= -
, then
x =
(
) = 60° ← related acute angle
Since sin x < 0 then x is in 3rd / 4th quadrants
x = 180° + 60° = 240°
x = 360° - 60° = 300°
