Answer:Associative Properties
Step-by-step explanation:
Answer:
84 degrees because both angles are equal.
The diameter of the circle is 8 cm, so the radius of the circle is R=4cm.
The Circumference of the circle is 2πR=8π cm
Let the measure of the central angle be x.
the arc that angle x intercepts is 8/8π=1/π of the circumference. (approximately 1/3.14 or 1 third, so x will be 1 third of 360°=2π rad)
this is the ratio that x forms to the full angle 2π rad

x= 2 rad.
Answer: 2 rad
Answer:
x = 8
Step-by-step explanation:
Interior angles of a triangle always add up to 180 degrees.
50 + 76 + ? = 180
? = 180 - 126
? = 54
A straight line also is always 180 degrees.
54 + 15x + 6 = 180
15x = 180 - 60
15x = 120
x = 8
