Given: /l1 m, 21 = 20x + 5; Z2 = 24x - 1 e
m
a. Using theorems pertaining to transverals and parallel lines, prove that mz1 + m 2 = 180°
b. Find the value of x.

can someone please show me the work or how to show the work for this question?

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
