Answer:
A regular polygon with each interior angle of 170 deg will have each exterior angle as 180–170 = 10 deg. Hence the number of sides in the regular polygon = 360/10 = 36 sides.
Hope this helps
Step-by-step explanation:
Answer:
86
Step-by-step explanation:
This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.
0.3 then 0.13 then 0.19 then 0.31
have a nice day ;)
Answer:
68:76.5
Step-by-step explanation:
create the ratio 68/x=8/9, then simplify the side you can so get 68/x=.8888... then multiply both sides by x to get rid of the fraction, 68=.8888...x. now divide both sides by .8888... to get x by itself, 76.5=x
if you have any questions, leave them int eh comments and i will try to answer them, if this helped, pls give brainliest
It means that when both sides of an equation have the same number subtracted from them the remaining expressions are equal. ( ......Hope that I helped you...... )
