I think the final angle is 5 sorry if that's not what you were looking for
Step-by-step explanation:
Area of rectangle= l x b
= 245 x 245
=60025
Area of triangle = (1/2) x b x h
=(1/2) x 245 x 245
=30012.5
Area of shaded part = Area of rectangle - Area of triangle
=60025 - 30012.5
=30012.5
<span>Interval between 2.6 minutes late and 8.2 minutes late is within 2
standard deviations of the mean (k =8.2â’5.4/1.4 =5.4â’2.6/1.4 = 2). By Chebyshev’s Theorem, at least 1 â’1/2^2 =3/4 of all flights, i.e. at least 75% of all flights arrive
anywhere between 2.6 minutes late and 8.2 minutes late.</span>
