Answer:

solution given :

side1[S1]=17cm

side2[S2]=21cm

side3[S3]=10cm

height[H]=8cm

we have .

Vector u has a magnitude of 5sq rt 3 feet and is directed due west. Vector v has a magnitude
Vikki [24]

The magnitude and the direction angle for  the resultant vector are 10N and 120degrees respectively

The formula for calculating the resultant vector is expressed as:

R^2 = u^2 + v^2\\R =\sqrt{u^2+v^2}

Given the following distances:

u = -5√3 feet (west direction)

v = 5 feet

Substitute the given values into the formula above;

R=\sqrt{(5\sqrt{3} )^2+5^2} \\R=\sqrt{(25 \times 3)+25}\\R=\sqrt{75 + 25}\\R=\sqrt{100}\\R = 10 feet

The magnitude of the resultant vector is 10feet

Get the direction:

\theta = tan^{-1}\frac{y}{x} \\\theta = tan^{-1}\frac{5}{-5\sqrt{3} }\\\theta =tan^{-1}\frac{-1}{\sqrt{3} }\\\theta = -60^0

Since tan is negative in the second quadrant, hence;

\theta = 180 - 60\\\theta = 120^0

Hence the magnitude and the direction angle for  the resultant vector are 10N and 120degrees respectively.
