Step-by-step explanation:
I solve this at my paper
Because completementary angles add up to 180 degrees (angle 3 and angle 4)

Answer:
975 bulbs
Step-by-step explanation:
1/40 bulbs were defective
That means 1-1/40 were not defective
40/40 - 1/40 = 39/40 were not defective
We have 1000 bulbs
Multiply the number of bulbs by the fraction that is not defective to get the number of bulbs that should not be defective.
1000 * 39/40 = 975 bulbs
