the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.
in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
7.9m and 4.3°
let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ
for 3.5 south, y = -3.5
for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30
for 15 west, x = -15
total x = 8.2 * cos 30 – 15 ≈ -7.9
total y = -3.5 + 8.2 * sin 30 = 0.6
magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5
the magnitude is approximately 7.9 m
tan θ = y/x = 0.6/-7.9
the angle is approximately 4.3˚ north of west
where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
