Well, all you have to do to solve this is multiply 850 times 10, which is 8,500, so that means there are 8 thousands.
PLEASE choose my answer as the Brainliest, as I have explained my answer well, and I am REALLY close to ranking up!
THANK YOU AND I HOPE I HELPED! =D
It is basically 8 thousand plus one thousand two hundred so your answer would be 9200
Things to remember the sum of the measures of the interior and exterior angles at each vertex is 180 (supplementary angles)
add and equal to 180
3x-5+5x+17= 180
8x+12=180
8x= 168
x=21
substitute in the algebraic expression for exterior angle
3(21) -5=
63-5=58
58 degrees is the exterior angle
hope this helps
