Hi there!
There are many ways to find the measure of an exterior angle of a triangle. I'll explain the easiest method to you. As you can see in the image, a line is drawn extending a side of the triangle. In order to find the measure of the exterior angle, we can subtract the measure of the
adjacent interior angle from 180 (a straight angle). Doing this subtraction will give us the measure of the exterior angle.
Hope this helps!! :)
Make them have the same denominator.
1/2 + 1/3
=3/6 + 2/6
=5/6
As you said it was dropped so in that case I'll take 78.4 meters as the height..
we know that
h = ut + 0.5*g*t(sqr)
t(sqr) = 78.4/(0.5*9.8) [g = 9.8 ms-2]
t = √16
t = 4
So it'd take 4 seconds
Check that the radar pistol has an error of 7 mph.
Then we have that:
59 mph - 7 mph = 52 mph approximately.
52mph <55mph
Answer:
He does not have irrefutable evidence that the car was speeding in a 55 mph zone
