Answer:
Step-by-step explanation:
Hello,
I assume that you know that
One way to retrieve them quickly is to use Euler's formula and then,
and you can replace B by -B for the second formula.
So, it comes that sin(A+B)-sin(A-B)=2cosAsinB
Hope this helps
from the formula given,
M= (x1+x2)/2
x1=10
x2=-6
(x1+x2)/2= (10+(-6))/2=(10-6)/2=4/2=2
you could also make x1=-6 and x2=10
(x1+x2)/2= (-6+10)/2=4/2=2
x = 3
2x + 7 =....
2 (3) + 7 = 6 + 7 = 13
this is my answer how about my answer ?
I hope this helps you
if two angles sum is 90 degree their name the relationship must be vertical.
a+b=90
