The time of a red light = 42 seconds
The time of a green light = 45 seconds
The time of a yellow light = 5 seconds
so,
All times = 42 + 45 + 5 = 92 seconds
Then
The probability to see a red light in one day = P(red)= (The time of a red light) ÷ (all tmes)
So, P(red) = 42/95
And
The probability to see a red light in five days = {P(red)}⁵ = (42/95)⁵
= 0.01689
= 1.689 %
Answer:83
Step-by-step explanation: A triangle is 180 degrees in total so if you take 90+45=135 then you subtract 52 from 135 and you get 83
so x=83
