Answer:
79.29
Explanation:
Given that,
The y component of a vector, y = 36
The angle between the vector and the x-axis is 27.
We need to find the magnitude of a vector.
Let a and b are x and y component of a vector m. There resultant is R. So,
Where
We have, b = 36 and θ = 27°
So,
So, the magnitude of the vector is 79.29
