Answer: 58

Step-by-step explanation:

Since the shape has 5 sides, the sum of the internal angles is (5-2)*180 = 3*180 = 540 degrees.

Therefore, 96+150+120+2x+x = 540

386 + 4x = 540

3x = 174

x = 58

2 gallons : 31 miles

Vika [28.1K]

15.5, because 31 divided by 2 is 15.5. And all the other number divided by the number below them also turns out to be 15.5.

Hope this helps. :)

Convert 58 mph to deet per second.

katovenus [111]

First we can change the miles per hours into feet per hour. Every mile is 5280 feet so multiply 58 by 5280. 58*5280=306,240. Now you have 306,240 feet per hour which you then divide by 60 twice to get per second. 306,240/60=5,104ft per minute now divide again to find per second. 5,104/60≈85.1feet per second.
