Answer:
A(n)=130+13(n-1) ; 86
Step-by-step explanation:
Here is the sequence
130,143,156,169.......
the first term denoted by a is 130 and the common difference denoted by d is second term minus first term
143 - 130 = 13
Hence a=130 and d = 13
Now we have to evaluate to 13th term.
The formula for nth term of any Arithmetic Sequence is
A(n) = a+(n-1)d
Hence substituting the values of a ,and d get
A(n)=130+13(n-1)
To find the 13th term , put n = 13
A(13)=130+13*(13-1)
= 130+13*12
= 130+156
A(13) = 286
I'm guessing the total amount of degrees is 360 degrees.
67 + 130 + 72 = 269
360 - 269 = 91
Answer = 91°
Hope this helped☺☺
The answer is C if not sorry
Given:
A bisector is a line or point that divides a line in half. So point M is in the middle of the entire line ST.
The bisector would be the line MW
This means line MT is half of the enitre line ST so then the entire line is 19*2.
Answer:
ST = 38
Bisector is line MW
