we know that

we know that

<u>Vertical angles</u> are congruent angles opposite each other where two lines cross

so

in this problem

m∠JNM=m∠KNL

so

substitute the values

4x+6=7x-21\\7x-4x=6+21\\3x=27\\x=27/3\\x=9\°

<u>Find the  m∠JNM</u>

(4x+6)=(4*9+6)=42\°

therefore

<u>the answer is</u>

The measure of angle JNM is 42\°

Somebody help me? I don't understand how it is solved (the factor thing is like saying x100 times)
shutvik [7]

sum of first n even nos =n(n+1)

sum of first n odd nos=n²

So

Simplify the numerator

  • x²x⁴x⁶..=x^(2+4+6..100times )

Simplify the denominator

  • xx³x⁵..=x^{1+3+5..100times)

Sum of first 100 even nos

  • 100(100-1)=100(99)=9900

Sum of first 100 odd nos

  • 100²=10000.

So

The equation yields as

  • E=x⁹⁹⁰⁰/x¹⁰⁰⁰⁰
  • E=1/x¹⁰⁰
