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

The area of a circle is A=πr².
Since π is about 3.14 we can substitute that into the equation.
So A=3.14×r²
We can substitute the given radius for r.
A= 3.14 × 5²
When a number is squared, or has the two over it, we multiply it by itself.
5 × 5= 25
A= 3.14 × 25
Simplify this and the area of the circle is about 78.5
A≈78.5
Answer:
18x + 48 = 20
Step-by-step explanation:
Rewrite the equation below so that it does not have fractions. 3/4x+2=5/6 do not use decimals in your answer.
We are given the expression:
3/4x + 2=5/6
= 3x/4 + 2 = 5/6
Rewriting the Equation so that it does not have fraction is, we Multiply both sides by the 24
= 3x/4 × 24 + 2 × 24 = 5/6 × 24
= 3x/4 × 24 + 48 = 5 × 4
= 3x × 6 + 48 = 20
= 18x + 48 = 20
Therefore, the Equation without fractions = 18x + 48 = 20
