C = 2*pi*r
So, C = pi*d
106.76 = pi*d
106.76/pi = d
d = ~33.98
So
a be first term and d be common difference
- a+a+2d+a+4d+a+6d+a+9d=17
- 5a+21d=17--(1)
And
- a+d+a+3d+a+5d+a+7d+a+9d=15
- 5a+25d=15--(2)
Eq(1)-Eq(2)
Put in second one
- 5a+25d=15
- a+5d=3
- a+5/2=15
- a=15-5/2
- a=25/2
Answer:
the distributive property is supposed to simplify your equation
Step-by-step explanation:
-4.2 - 6y + 3.6
Complimentary means 90 degree angle so 90-41.4= the complimentary angle which is 48.6. Supplementary means 180 degrees so 180-41.4= the supplementary angle which is 138.6..
