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 $x$ :

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

Here, y = -15 with x = -20
LCM of 15 & 20 is 60, so divide 15 & 20 from 60,
60/15 = 4 & 60/20 = 3

Now, multiply the results with intial values,
4y = 3x
y = 3/4 x

When y = 12,
x = 12 * 4/3
x = 48 / 3
x = 16

In short, Your Answer would be 16

Hope this helps!
