Answer:
Step-by-step explanation:
Given:
The given equation is 
We need to solve the given equation for r.
Rewrite the equation as.
Divide both side of the equation by 4π and simplify
Take the square root both side of the equation.
Therefore, the solution for r is both positive or negative
Answer:
24.4
Step-by-step explanation:
tan(16) = opposite/adjacent
tan(16) = 7/YZ
YZ = 7/tan(16)
YZ = 7/0.287
YZ = 24.39
YZ = 24.4
Answer:
∠ ABE = 46°
Step-by-step explanation:
Since BE bisects ∠ ABC , then
∠ EBC = ∠ ABE, substitute values
4x - 6 = 2x + 20 ( subtract 2x from both sides )
2x - 6 = 20 ( add 6 to both sides )
2x = 26 ( divide both sides by 2 )
x = 13
Thus
∠ ABE = 2x + 20 = 2(13) + 20 = 26 + 20 = 46°
