Answer:
Step-by-step explanation:
Given information: |a| = 80, |b| = 50, the angle between a and b is 3π/4.
We need to find the dot product a · b.
The formula of dot product is
where, θ is the angle between a and b.
Substitute the given values in the above formula.
Rationalize the above equation.
Therefore, the value of a · b is .
