<span>Quadrilateral has to equal 360 degrees.

So simply subtract. 

360 - 101 - 133 - 76 equals... 50

Then you can add to see if they all equal 360.


</span>101 + 133 + 76 + 50 = 360
<span>
So the answer is 50.

Hope this helps. c:

The sum of angles in a quadrilateral = 360 degrees.

Let the fourth angle be y

101 + 133 + 76 + y = 360

310 + y = 360

y = 360 - 310

y =50

Therefore the fourth angle is 50°

Hope this explains it.

A plumber had a pipe that was 2 yards long he cut 18 inches off the end of the pipe
balandron [24]
To convert yards to feet, you would multiply it by 3. So, since there the pipe is 2 yards long, you could multiply 2*3 to get 6 feet. Then you can convert feet to inches by multiplying it by 12. 6*12 is equal to 72, so 2 yards is equal to 72 inches. Lastly, you can subtract 18 from 72, to get 54, and 54 inches would be your final answer.
