step 5
Find the perimeter

Answer: 56 degree
Explanation:
2x + 16 + 3x + 2 + 2x + 2x = 180 (straight angle)
9x + 18 = 180
9x = 162
x = 162/9
x = 18
But WSV = 3x + 2
And x = 18
=> 3(18) + 2
=> 54 + 2 = 56
Let us assume that the given speed is in miles per hour.
A race car is driven by a professional driver at 99 mph.
We have to find the speed in kilometer per hour and kilometer per minutes
As 1 mile = 1.61 km
So, 99 miles =
kmph
1 km per hour = 0.0166 km per minute
So, 159.39 kmph =
km per minute
Hence, The speed is equivalent to 159.39 kilometers /hour, or 2.645 kilometers/minutes .
