Answer: DC=30.5
Step-by-step explanation:
Use trigonometry to solve this question
----------------------------------------------------------
First Step: find BD
- AB relative to 54° is [hypotenues]
- BD relative to 54° is [opposite]
- Therefore, we need to use O/H, which is Sin
- sin(54°)=O/20=20·sin(54°)=16.2
Second Step: Find DC
- DC relative to 28° is [adjacent]
- BD relative to 28° is [opposite]
- Therefore, we need to use O/A, which is tan
- tan(28°)=16.2/A=16.2/tan(28°)=30.5
Hope this helps!! :)

$27.6</h2><h2>
</h2>
Step-by-step explanation:
$24 + 15%
just multiply by 1.15
$24 x 1.15 = $27.6
Answer:
19.47°
Step-by-step explanation:
2 = opposite to A
6 = hypotenus
From trigonometry :
Sin A = opposite / hypotenus
Sin A = 2 / 6
Sin A = 1/3
A = sin^-1(1/3)
A = 19.47°
