Answer:
C ≈ 54
Step-by-step explanation:
The circumference (C) is calculated as
C = πd ( d is the diameter )
Here d = 18 , then
C = π × 18 ≈ 3 × 18 = 54
all except for d are function because d has the same x more than once
Answer:
m∠EBC=34°
Step-by-step explanation:
we know that
m∠DBC=m∠DBE+m∠EBC
see the attached figure to better understand the problem
substitute the given values in the formula and solve for x
Find the measure of angle EBC
m∠EBC=(3x+13)°
substitute the value of x
m∠EBC=(3(7)+13)°
m∠EBC=(21+13)°
m∠EBC=34°
