The answer is B, or 55˚
When angles are complementary, that means that their sum equals 90˚. First, we need to find out what the measure of angle 2 is, so to do this, we can subtract the sum of angle 1 and angle 2 by the measure of angle 1
Their sum is 90, and angle 1 is 35. So angle 2 = 90 – 35 = 55.
So now we know angle 2. And since angle 2 = angle 3, and angle 3 = angle 4, angle 4 is the same as angle 2. So, angle 4 = 55˚
