This acute triangle is equal to 63
Answer:
15
Step-by-step explanation:
The magnitude of the vector C that satisfies the expression is 6.48m
Given the following magnitude;
Vector A = 5.1m
Vector B = 4.0m (upward)
Taking the resultant vector of A and B we will have:

Given the expression A⃗ +B⃗ +C⃗ =0⃗
R + C = 0
C = 0 - R
C = 0 - 6.48
C = -6.48m
Hence the magnitude of the vector C that satisfies the expression is 6.48m
