352, 345, 338, ...<br> Find the 43rd term.
Artemon [7]

Answer:

Step-by-step explanation:

first term = a = 352

Common difference = d = second term - first term

                                  = 345 - 352

                                   = (-7)

nth term = a + (n-1)*d

43rd term = 352 + (43-1)*(-7)

                 = 352 + 42 *(-7)

                  = 352 - 294

                  = 58

Find the value of x ?<br><br> A)67<br><br> B)113<br><br> C)77<br><br> D)57
lana [24]

Answer:

<h2>A) 67</h2>

Step-by-step explanation:

The sum of the angles measures at one side of the parallelogram is 180°.

Therefore we have the equation:

x + 113 = 180             <em>subtract 113 from both sides</em>

x + 113 - 113 = 180 - 113

x = 67
