If the measure of angle 4 is 94°, each angle congruent to it will be 94°. Angles 2, 4, 6, and 8 are the same and the angles 1, 3, 5, and 7 are the same. The straight line (I believe it's a transversal) divides the parallel lines and it is slightly tilted, which is why angles 2, 4, 6, and 8 are 94° instead of 90°.
The angle of say, 2 and 3 added, is equal to 180° which makes it supplementary. That means if we know angle 2 is 94°, we can subtract that from 180° to find the angle of 3 and the subsequent odd angles. 180 - 94 = 86 so angles 1, 3, 5, and 7 are 86°.
Hope this helps
