jimthompson5910 (jim_thompson5910):

What is the interior angle of a square?

OpenStudy (anonymous):

90 degrees

jimthompson5910 (jim_thompson5910):

how about an equilateral triangle?

OpenStudy (anonymous):

60

jimthompson5910 (jim_thompson5910):

we have 2 triangles and 1 square so 90 + 2*60 = 90 + 120 = 210

jimthompson5910 (jim_thompson5910):

we now need 360 - 210 = 150 more degrees to fill up the space

jimthompson5910 (jim_thompson5910):

so which answer choice has 150 as the result?

OpenStudy (anonymous):

D !!!! :D

Here is the image of putting a square with 2 equilateral triangles |dw:1404619490717:dw|

jimthompson5910 (jim_thompson5910):

we can see that they take up 90+60+60 = 210 degrees |dw:1404619562042:dw|
