Answer 5

what do you know about the sum of the interior angles of a quadrilateral?

Answer 6

hint: a square is a quadrilateral, too

Answer 7

I know that The sum of any shape's interior angles (The angles inside the shape made where the sides meet) can be found using the equation
(n-2)*180 where n=the number of sides the shape has. A quadrilateral has four sides so
(4-2)*180
2*180
360
The sum of a quadrilateral's interior angles is 360 degrees.

Answer 8

right. so you can write an equation for the sum of the angles and set it equal to 360, then solve for the value of x.

Answer 9

these are the options by the way

Answer 10

(x + 16) - (6x − 4) = 180

(x + 16) + (x) = 90

(2x + 16) + (x) = 180

(x + 16) − (x) = 90

Answer 11

but none of these have 360 in them?

Answer 12

im thinking it will be 2x + 16) + (x) = 180

Answer 13

besides the interior angles summing to 360, the opposite angles will sum to 180

Answer 14

yeah I checked them and the answer choices where right I coppied and pasted them

Answer 15

yeah, I'd go with the 3rd one.

Answer 16

nevermind Im just going to guess on this one can you help me with another question please

Answer 17

I'm a little puzzled as to why the solution to that equation isn't giving us an answer that satisfies the sum of all 4 = 360, but maybe it's just a lack of coffee so far

Answer 18

yeah lol its confusinf for me too

Answer 19

well, what's the other question?
