Answer:
Step-by-step explanation:
∠XBC = 55°
XB = XC. So, ΔXBC is an isosceles triangle
∠XCB = ∠XBC
∠XCB = 55°
In ΔXBC,
∠BXC + ∠XBC + ∠XCB = 180 {Angle sum property of triangle}
∠BXC +55 +55 = 180
∠BXC + 110 = 180
∠BXC = 180 -110
∠BXC = 70°

Answer:
Circumference of a circle=
Step-by-step explanation:
The circumference of any circle is the total length of its boundary which can be calculated by the formula:
Circumference of a circle=
Where 'r' is the radius of the circle
For, the given circle the circumference can be find in terms of by putting some value of radius in the formula, which gives the circumference in terms of .
