Step-by-step explanation:
4/5 divide
0.8 is the ans
Answer:80 degree angle
Step-by-step explanation:
There are always 180 degrees so you subtract the 2 others and you get the angle (60+40-180)
the sequence is 4n-13, so substitute 107 into n and it will become 4(107)-13 =415
?????????????????????/ us a calculator to add up all the nub.
Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 18) / 4) + 18
C = (56.52 / 4) + 18
C = 14.13 + 18
C = 32.13 miles
Hope this helps! :)
