Which rule will find the nth term of the arithmetic sequence -58, -65, -72, -86, …?
A. an = -65 − 7n
B. an = -65 + 7n
C. an = 51 − 7n
D. an = -51 + 7n
E. an = -51 − 7n

See below

Step-by-step explanation:

The triangles ΔTYW and ΔZYW are congruent because

TY = ZY,

YW is common and

the included angle is of same measure, ∠TYW = ∠ZYW = 90°

- SAS theorem

18.

TW = WZ

2x = 3x - 5

3x - 2x = 5

x = 5

19.

TW = 2x = 2*5 = 10

20.

WZ = TW = 10

21.

Triangle TWZ is isosceles
