(6.72×10^9)÷(3.2×10^2)=2.1×10^7
6.72÷3.2=2.1 and
10^9÷10^2=10^7 {here power is subtracted 9-2=7}
2.1×10^7

Answer:
- 35°
- 145°
- 55°
- 125°
- 55°
Step-by-step explanation:
The right triangles are similar, so angle 1 is congruent to the given angle, and angles 3 and 5 are complements of that.
Angles 2 and 4 are the supplements of angles 1 and 5, respectively.
∠1 = 35°
∠2 = 180° -35° = 145°
∠3 = ∠5 = 90° -35° = 55°
∠4 = 180° -55° = 125°
Answer:
57⁰
Step-by-step explanation:
a triangle's angles add up to 180⁰ total
44+79=123
180-123=57
Answer:Prove that for any nonzero natural
n
it is true that
Sn=1+1/4+1/9+1/16+1/25+1/2<2
I'm sort of at a loss here. I'm not sure if there exists some formula or method to sum this kind of series, since there is a variable ratio…
