The complete question in the attached figure
we know that
sin40° = opposite side / hypotenuse
opposite side =AC
hypotenuse = AB-------> 10 in
so
sin 40=AC/AB---------> AC=AB*sin 40-------> AC=10*sin 40
the answer is
AC=10*sin 40
Answer: B, Each of the sums is 180 degrees.
Step-by-step explanation:
Since a 180 degree angle is always a flat line, and that is the case for this,
Each of the sums is 180 degrees.
I believe it is a but i will double check and post ok
Answer:
the quotient is keeping batman alive
Answer:
The correct answer is the last option.
Step-by-step explanation:
When you have a fraction with complex numbers, the first step to simplify is to multiply up and down the conjugate of the denominator, this will eliminate the complex part of the denominator, and in this way you can separate the expression in its real and complex part.
For the expression:

The denominator conjugate is 4 + 2i
When multiplied, the denominator is:
