Explanation:
[I'm assuming you want us to find the measure of ∠ABC]
∠ABC is a right angle, meaning ∠ABD and ∠DBC added together must equal 90°
2x° + 3x° = 90
2x + 3x = 5x
5x = 90
5x / 5 = 90 / 5
x = 18
Determine the ratio of defective telephones
ratio = 9/30
ratio = 3/10
3 of 10 telephones are defective
Determine the number of defective telephones each day
def telephone = ratio of defective × total production
def telephone = 3/10 × 1000
def telephone = 300
There are 300 defective telephones each day
