Correct Answer: Option E
Explanation:
tan\(\theta\) = \(\frac{0.8}{2}\) = (0.4)
\(\theta\) = tan-1(0.4)
From the diagram, the inclination of the diagonal PR to the horizontal is 10o 42'
tan\(\theta\) = \(\frac{0.8}{2}\) = (0.4)
\(\theta\) = tan-1(0.4)
From the diagram, the inclination of the diagonal PR to the horizontal is 10o 42'
