A quadrilateral has its interior angles X, 47, 95, 82. Find<br>the value of x

Oksana_A [137]

Answer:

x=136

Step-by-step explanation:

To find the measure of the sum of the interior angles use the formula (n-2) times 180 where n is the number of sides.

A quadrilateral has 4 sides. (4-2) times 180. 2 times 180=360

The sum of the interior angles of a quadrilateral is 360.

x+47+95+82=360

x+ 224 = 360

x= 136

polet [3.4K]

Answer:

-85

Explanation:

Given the mathematical expression:

$-18+(-67)$

First, we recall the product of signs.

$+\times-=-$

So, first, we open the bracket:

$-18+(-67)=-18-67$

We then simplify:

$=-85$

The result is -85.
