Note that you are adding the parenthesis together. In this case, you can disregard the parenthesis. Combine like terms (terms with the same amount of variables):

2x + 1x - 3 + 2

(2x + 1x) + (-3 + 2)

3x + (-1)

3x - 1

3x - 1 is your answer.

Number of sides of shape: 4 Number of degrees inside:

Nutka1998 [239]

Answer:

360°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 4, hence

sum of interior angles = 180° × 2 = 360°

How would I solve for x?

vaieri [72.5K]

Answer:

$x = 65$

Step-by-step explanation:

First, we calculate the unknown angle of the left triangle and right triangle: $180 - 62 - 50 = 68$

Unknown angle for left triangle⬆️

$180 - 80 - 53 = 47$

Unknown angle for right triangle⬆️

Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

$180 - 68 - 47 = 65$

The angle 65° and angle of x are vertical angle.(both are equal)

So... x= 65°

hope it helps :)
