m∠ZAB + m∠CAB = 180° by the angle addition postulate
m∠CAB + m∠ACB + m∠CBA = 180° because of the triangle angle sum theorem
m∠ZAB = m∠ACB + m∠CBA using the subtraction property
<h3>What is an equation?</h3>

Answer:
4%
Step-by-step explanation:
The question here says that an online retailer conducts a random survey of its customers. The survey shows that 80% of the customers receive their purchases within four days, and 95% of those customers are satisfied with the quality of their purchase What percent of all customers receive their purchase within four days and are not satisfied with the quality of their purchases?
----80% of all their customers receive their goods within 4 days AND
----95% of the 80% of the customers are satisfied with the quality of their purchase.
---Therefore only 5% of the customers that received their purchased within 4 days are the ones not satisfied with the quality of the purchase.
The percentage of customers that received their purchases and yet still not satisfied with the quality out of all their customers (both the ones that received in 4 days and the ones that receive after 4 days) will be
80% of customers receive within 4 days
95% are satisfied with the quality
5% are not satisfied
5/100 × 80 = 4%
