Answer:
1.17 units
Step-by-step explanation:
Given :
If x = 45, y = 63, and the measure of AC = 4 units, what is the difference in length between segments AB and AD?
x= 45° ; y = 63° AC = 4 units
From trigonometry,
Taking triangle ADC;
sinθ = opposite / Hypotenus
Sin63° = 4 / AD
AD = 4 / 0.891 = 4.489 units
From triangle ABC;
sin45° = 4 / AB
AB = 4 / 0.7071
AB = 5.656 units
Difference = (5.657 - 4.489) units
= 1.167 units
= 1.17 units (nearest hundredth)
