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 $x$ :

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

Answer:

$\boxed{\dfrac{1}{2} = m}$

Step-by-step explanation:

Given equation:

$\dfrac{3}{4} = m + \dfrac{1}{4}$

<u>Step-1: Subtract 1/4 both sides</u>

$\dfrac{3}{4} = m + \dfrac{1}{4}$

$\dfrac{3}{4} - \dfrac{1}{4} = m$

$\dfrac{2}{4} = \boxed{\dfrac{1}{2} = m}$
