Answer:
Step-by-step explanation:
- <em>Sum of exterior angles of any polygon is 360°</em>
<h3>Exercise 8</h3>
<u>Sum of given angles:</u>
- 2x + 60° + 64° + 36° + 48° = 360°
- 2x + 208° = 360°
- 2x = 360° - 208°
- 2x = 152°
- x = 76°
<h3>Exercise 9</h3>
<u>Sum of given angles:</u>
- x + 90° + 109°+ 73° = 360°
- x + 272° = 360°
- x = 360° - 272°
- x = 88°
Answer:
<h3>dn = -7^n-1</h3>
Step-by-step explanation:
Given the sequence -1,-7,-49,-343,....
We are to find the nth term of the sequence
dn = ar^n-1
a is the first term = -1
r is the common ration = -7/-1 = -49/-7 = 7
n is the number of terms
Substitute
dn = -1(7)^n-1
dn = -7^n-1
hence the nth term of the sequence is dn = -7^n-1
A would be correct!!!
Glad I could help(:
