We know that:
C=πd Were π(pi)=3,14... and d=diameter
We know that the radious is 2d, so we aply this to the formula and we get that:
C=2πr

A, B &amp; C lie on a straight line.
Liono4ka [1.6K]

Answer:

x = 129°

Step-by-step explanation:

∠ ABD and ∠ DBC are a linear pair and sum to 180° , then

y + ∠ DBC = 180°

107° + ∠ DBC = 180° ( subtract 107° from both sides )

∠ DBC = 73°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , then

x = ∠ DBC + z = 73° + 56° = 129°
