Answer:
300,000 8,000 800 i think sorry if i got it wrong
Step-by-step explanation:
We have that
2sin²<span>x - sinx - 3 = 0
</span>
Let
A------> sin x
so
2A²-A-3=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solutions are
A=-1
A=1.5------> is not solution because sin x <span>can not be 1.5
the solution is
A=-1
therefore
sin x=-1
x=arc sin(-1)=-90</span>°
the answer is
sin x=-1x=-90° or 270°
Answer:
180
Step-by-step explanation:
=216-(-83)+(-479)
=216+83-479
=299-479
=180
