Answer:
a) Angle XBC = 55 because XY is parallel with BD
b) As given, XB = XC, so that triangle XBC is the equilateral triangle.
As XBC is equilateral triangle, angle XBC is equal to angle XCB
Angle XBC = 55° => Angle XCB = 55°
In a triangle, the total value of three corners are equal to 180°
So that: Angle XBC + Angle XCB + Angle BXC = 180°
=> 55° + 55° + Angle BXC = 180 °
=> Angle BXC = 70°
<h3>
Answer:</h3>
18.8 feet
<h3>Step-by-step explanation:</h3>
We are given;
Radius of the fountain is 9.4 feet
We are required to determine the diameter of the fountains
We need to know that the diameter of a circle is twice the radius of the circle.
That is;
Diameter = 2r
Therefore;
Diameter of the fountain = 2 × 9.4 feet
= 18.8 feet
Thus, the diameter of the fountain is 18.8 ft
