Answer:

x=85^{\circ}

Step-by-step explanation:

The sum of the interior angles of any polygon with five sides is equal to (5-2)\cdot 180=3\cdot 180=540^{\circ}. Therefore, we can set up the following equation and solve for x:

115+95+115+130+x=540,\\455+x=540,\\x=\boxed{85^{\circ}}

Three less than two times a number is 55. What’s the number ?
Musya8 [376]

Let n be a number

2n - 3 = 55

Add 3 to both sides

2n + (-3 + 3) = 55 + 3

2n = 58

Divide 2 to both sides

2n/2 = 58/2

n = 29

Hope this helped!
