Please help me now please

ahrayia [7]

Answer:

A = 110 degrees.

Step-by-step explanation:

< A and < B are same side angles so their values add up to 180 degrees, so:

5x + 20 + 9x - 92 = 180

14x - 72 = 180

14x = 252

x = 18.

So m A = 5(18) + 20

= 110 DEGREES.

What is the 97th term of the arithmetic sequence -16,2,20

MAXImum [283]

Answer:

1712

Step-by-step explanation:

Given arithmetic sequence is: -16,2,20

Here, a = - 16, d = 2 - (-16) = 2+ 16 = 18

n = 97, $a_{97}=?$

$\because a_n = a + (n-1)d\\\\\therefore a_{97}= - 16 + (97-1)\times 18\\\\\therefore a_{97}= - 16 + 96\times 18\\\\\therefore a_{97}= - 16 + 1728\\\\\therefore a_{97}=1,712\\\\$
