Step-by-step explanation:

Let us take ratio constant as 'x'

Therefore ratio of angles

3x:5x:9x:13x

Sum of interior angles of quadrilateral is 360 degree.

3x+5x+9x+13x=sum of interior angles of quadrilateral

=>3x+5x+9x+13x=360

=>30x=360

=>x=12

What is 89+27+11 using a mental math property
timofeeve [1]
Everyone works differently in mental math.

Using the property of commutativity, we can (mentally) rearrange to calculate 89+11  + 27
Since 89+11 is exactly 100, the sum is therefore 100+27=127.
