Determine the value of x for which r ∥ s if m∠1 = 40 – 4x; and
m∠2 = 50 – 8x

The choices are
2.5

2

30

1.5

2.5

Step-by-step explanation:

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
