Can any body here prove that 1-1+1-1+1-1+1-1.........=1/2 <br>And What is known as this series?​
Rina8888 [55]

Answer:

This is known as grandi's series, the proof is in the explanation

Step-by-step explanation:

grandi's series, S_G is given by = 1-1+1-1+1-1+1-1...

1 - S_G = 1 - (1-1+1-1+1-1+1-1) = 1-1+1-1+1-1+1-1 = S_G

1- S_G = S_G

S_G + S_G = 1

2S_G = 1

S_G = 1/2

Find measure of angle E
ki77a [65]

The measure of ∠E will be equal to 38°.

Given,

m∠BFE = 118° and m∠C = 86°

And BF bisects ∠ABD

From the Property of Linear Pair,

∠AFB + ∠BFE = 180°

=> ∠AFB + 118° = 180°

=> ∠AFB = 62°

Now, we can see that ∠AFB and ∠FBD are equal because they are alternate angles.

And ∠FBD and ∠ABF are equal because BF bisects ∠ABD.

So, In ∆ABF,

∠AFB + ∠ABF + ∠BAF = 180° (because of the angle sum property of a triangle)

=>62° + 62° + ∠BAF = 180°

=>∠BAF = 180° - 124°

=> ∠BAF = 56°

Similarly, in ∆ABE,

∠A +∠C  +∠E = 180°

=> 56° + 86° + ∠E = 180°

=> ∠E = 38°

Therefore, m∠E = 38°.
