5. Lines p and q are parallel, and line w is a transversal. Which angle is not congruent to angle 1? ​
Tamiku [17]

Answer:

∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.

Step-by-step explanation:

From the picture attached,

p and q are the parallel lines and w is a transversal.

∠1 ≅ ∠3 [Vertically opposite angles]

∠1 ≅ ∠5 [Corresponding angles]

∠1 ≅ ∠7 [Alternate exterior angles]

Therefore, ∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.

the 43rd term of an arithmetic sequence is -671 and the 52nd term is -806. find the first term and the common difference.
Bond [772]

Answer:

First term = -41.

Common difference = -15.

Step-by-step explanation:

nth term: an = a1 + (n - 1)d  where a = first term and d = the common difference.

-671 = a1 + (43 - 1)d

-806 = a1 +(52 - 1)d

-671  = a1 + 42d

-806 = a1 + 51d

Subtracting ( to eliminate a1):

-671 - (-806) = 42d - 51d

-9d =  135

d = -15

Substitute for d in the first equation:

-671 = a1 + 42*-15

-671 = a1 - 630

a1 = -671 + 630 = -41.
