Aquadrilateral has angles that measure 125°, 115°, and 65°. what is the measure of the fourth angle?

Hello! A quadrilateral has 4 angles that equal 360 degrees. You already have three that equal 125 degrees, 115 degrees, and 65 degrees. Those three angles when added up have a sum of 305 degrees. Then, you subtract that number from 360 to find your fourth angle. 360 - 305 = 55. The measurement of the fourth angles is 55 degrees.

Has to be 55 degrees, as all four add to 360.

one of each metals

step-by-step explanation:

What are the options

If the Angles are 125 + 150+ 65 then the missing angle is 20.

Step-by-step explanation:

All angles need to add up to 360 degrees.

The measure of the fourth angle = 55°

Step-by-step explanation:

Sum of all 4 interior angles in a quadrilateral = 360°

Let x = the measure of the fourth angle

x + 125°+ 115°+ 65° = 360°

x + 305° = 360°

x = 360° - 305°

x = 55°

The answer is 11 degrees
