Answer:

 ∠b = 88 - 5x

Step-by-step explanation:

If a and b are complementary, then sum of two angles is 90

∠a + ∠b = 90

5x + 2 + ∠b = 90

             ∠b = 90 - 5x - 2

             ∠b = 88 - 5x

A sidewalk around a circular park covers a distance of 65 meters. A new sidewalk is being constructed across the park through it
lidiya [134]

All we have to do is divide the distance of the old sidewalk by 3.14:

65 / 3.14 ≈ 20.7006

That means that, rounded to the nearest meter, the new sidewalk is:

21 meters long!

Show that n(n+1)(n+2) is divisible by 6<br>Solution<br>(​
vladimir2022 [97]

Proof by induction

Base case:

n=1: 1*2*3=6 is obviously divisible by six.

Assumption: For every n>1 n(n+1)(n+2) is divisible by 6.

For n+1:

(n+1)(n+2)(n+3)=

(n(n+1)(n+2)+3(n+1)(n+2))

We have assumed that n(n+1)(n+2) is divisble by 6.

We now only need to prove that 3(n+1)(n+2) is divisible by 6.

If 3(n+1)(n+2) is divisible by 6, then (n+1)(n+2) must be divisible by 2.

The "cool" part about this proof.

Since n is a natural number greater than 1 we can say the following:

If n is an odd number, then n+1 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted.

If n is an even number" then n+2 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted.

Therefore by using the method of mathematical induction we proved that for every natural number n, n(n+1)(n+2) is divisible by 6. QED.
