Question

Lines l and m are parallel.
Parallel lines l and m are intersected by lines s and t. At the intersection of lines l, s, and t, clockwise from the top left, the angles are blank, 50 degrees, (x + 25) degrees, (2 x) degrees, 1, blank. Lines t, s, and m create a triangle with angles 1, 2, 3.
Use the diagram to determine the measure of ∠3.

Answer 1

Answer:

The answer is 70 degrees

I got it on Edge 2021:)

Answer 2

In the attached photo we can see 's' is a straight line.

So, the sum of angles on line 's' will be 180 degree

50 + x + 25 +2x = 180degree

75 + 3x = 180

3x = 180 - 75

3x = 105

x = 35

From diagram,

∠3 = 2x  [alternative interior angle]

∠3 = 2*35

∠3 = 70degree

Hence, measure of ∠3 is 70 degree
