Question

Drag the correct answer to the image. Determine the missing angle measure of the quadrilateral. 60° 120° 100° 3 .: 90° .: 750 :: 800 :: 700 hun

Answer 1

Solution

For this case we need to remember that the sum of the interior angles is 360º

And then we have the following:

60 +120 + 100 +x = 360

And solving for x we got:

x= 360 -120 -100 -60= 80

And the best oslution would be:

80º
