The actual wind resistance is also an independent lognormal random variable with a mean of 90 and standard deviation of 13.5. failure in the antenna will occur whenever the maximum wind pressure exceeds its wind resistance capacity. during a wind storm, what is the probability of failure of antenna?
supplementary angles add up to 180°
so the answer would be 180-117 = 63
radius = 5 in
using the formula for calculating the area (a) of a circle
a = πr² ( r is the radius )
here a = 78.5, hence
3.14r² = 78.5 ( divide both sides by 3.14 )
r² = = 25 ( take the square root of both sides )
r = = 5
hi my dear friend,
a bisector is a line that intersects two or more lines in different points.
