<WSN=80
Step-by-step explanation:
arc WN = 160
<wsn= 1/2 of arc WN
The explicit rule for the arithmetic sequence for the sequence is a(n) = 3n + 2.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have given:
and


The above expression represents the common ratio:
d = 3
First term:
a = 5
The explicit rule for the arithmetic sequence:
a(n) = 5 + (n - 1)3
a(n) = 3n + 2
Thus, the explicit rule for the arithmetic sequence for the sequence is a(n) = 3n + 2.

#SPJ1
Answer:
35
Step-by-step explanation:
Since all the angles are the same in this triangle, all the sides should be the same too.
Hence, 3x - 5 = 4x - 30
5 + -1x = -30
-1x = -35
x = 35
Hope this helped!
A = 1/2 BH
#17
B = 3 H = 4
A = 1/2 BH
A = 1/2 (3)(4) = 6
#18
B = 6 H = 4
A = 1/2 BH
A = 1/2 (6)(4) = 12
#19
B = 12 H = 8
A = 1/2 BH
A = 1/2 (12)(8) = 48
#20
B = 11 H = 5
A = 1/2 BH
A = 1/2 (11)(5) = 27.5
