Answer:
Step-by-step explanation:
Given
Required
Complete the triangle (See attachment)
First, calculate side a using cosine's equation
Take square roots
The measure of B and C can then be calculated using sine's equation
So:
Cross multiply
Solve for sin B
Take arc sin of both sides
To calculate C, we make use of:
--- angles in a triangle
Collect like terms
A. semi

Answer:
10+15i/13
Step-by-step explanation:
This question is about complex numbers.
so,
in this type of questions we have to multiply this fraction by the conjugate of the denominator
conjugate of the denominator is 3-2i
1) 5i(3-2i)/(3+2i)(3-2i)
2) 15i-10i^2/9-4i^2 ( we know that i^2 = -1 )
3) 15i+10/9+4
4) 15i+10 / 13
