Answer:

m∠1 = 52, m∠2 = 60

Step-by-step explanation:

68 and ∠2 are interior angles. 128 is exterior angle.

Formula : -

Sum of two interior angles = Exterior angle

68 + ∠2 = 128

∠2 = 128 - 68

∠2 = 60

∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,

∠1 + 128 = 180

∠1 = 180 - 128

∠1 = 52

Answer:

x=12

Step-by-step explanation:

To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.

Therefore, we can set up an equation with one of the angles:

7x+6=90

7x=84

x=12

The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:

8*12-6=96-6=90

Therefore, x=12.
