XY and BD are parallel lines.
X is a point on AB and C is a point on BD.
XB = XC.
a) Complete this sentence.
Angle XBC = 55⁰ because

b) Work out angle BXC.
Give a reason for each angle you work out.

Hey  i got the top one its AXY and XBC ar corresponding angles

Step-by-step explanation:

help it helps you ,i will look and try to do the bottom one aswell, kan you mark me the brainlist pls.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
