Lines l and m are parallel. Parallel lines l and m are cut by transversals s and t. Clockwise from top left, the angles formed b

denis-greek [22]

Answer:

25 degrees

Step-by-step explanation:

In the picture attached, the lines and the angles are shown. There we can see that:

85° + 2x° + (x-10)° = 180°

75 + 3x = 180

x = (180 - 75)/3

x = 35°

∠3 and ∠(x-10)° are alternate interior angles, therefore they are congruent, so:

∠3 = x - 10

∠3 = 35 - 10

∠3 = 25°

What value of z makes the statement true?

Shkiper50 [21]

-(z + (-17)) = 12 + 17

-(z - 17) = 12 + 17

Distribute -1:

-z + 17 = 12 + 17

Subtract 17 to both sides:

-z = 12

Multiply -1 to both sides:

z = -12
