1. T =34

2.143 =exterior A

**Step-by-step explanation:**

The sum of the angles in a triangle is 180 degrees

T+H+E =180

T + 107+39 = 180

Combine like terms

T +146 = 180

Subtract 146 from each side

T +146-146 = 180-146

T =34

The exterior angle is the sum of the opposite interior angles in a triangle.

B+T =exterior A

66 +77 = exterior A

143 =exterior A

336 Hours = 1,209,600 Seconds = 1209600 Seconds

**Step-by-step explanation:**

This conversion of 336 hours to seconds has been calculated by multiplying 336 hours by 3,600 and the result is 1,209,600 seconds.

1. Geometric sequence

2. 4,096

3. 5,460

**Step-by-step explanation:**

Part 1

Since the number of letters sent is multiplied by 4 for any subsequent term, the sequence is an example of a **geometric sequence** as it grows exponentially.

Part 2

Given a geometric sequence, the nth term is determined using the formula:

In this case,

a=1 (i.e. Nchathamtownfc.neth)

r=4

Since we want to determine how many letters will be sent on the sixth mailing(i.e after Nchathamtownfc.neth), n=7

Substituting

Part 3

To determine how many people would have participated by the sixth mailing, we are required to find the **sum of the first seven terms** of the geometric sequence.

We use the sum of a geometric sequence formula

Therefore, excluding Nchathamtownfc.neth, 5460 people would have participated by the sixth mailing.
