Step-by-step explanation:
x is greater or equal to 13
35 + 52 + 3(x + 2) = 180
87 + 3x + 6 = 180 ( add the like terms and use distributive property)
93 + 3x = 180
-93 -93
3x = 87
÷3 ÷3
x = 29
( the sum of all triangle angles is 180)

In 2 hours, the car will travel ...
distance = speed · time = (90 km/h)(2 h) = 180 km
What you have to do is add all of the numbers:
5.98 + 16.39 + 2.25 + 2.29 =
