Apair of parallel lines is cut by a transversal, as shown: a pair of parallel lines is shown cut by a transversal. angle a is located in the upper left exterior next to the transversal, and angle b is located in the bottom right exterior corner of the transversal. which of the following best represents the relationship between angles a and b? a = b a = 180 degrees − b b = 180 degrees − a a = 2b

A = B

Step-by-step explanation: I think this answer is correct because they both are the same angle and on opposite sides of the line. Also, on my test i got it correct.

A = B

Step-by-step explanation:

Let the parallel lines m and n cut by a same transversal such that,

Angle A is the upper left exterior next to the line t and angle B is located in the bottom right exterior corner of the line t, ( shown below ),

By the alternate exterior angle theorem,

m∠A = m∠B

I.e. FIRST option is correct.

the answer is a

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
