Answer:
Θ = 46°
Step-by-step explanation:
the angle between a tangent and a radius at the point of contact is 90° , so
∠ ABO = 90°
since OB = OD ( radii of circle ) then Δ BOD is isosceles and
∠ OBD = ∠ ODB = 22°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ AOB is an exterior angle of the triangle , then
∠ AOB = 22° + 22° = 44°
the sum of the 3 angles in Δ AOB = 180° , then
Θ + 44° + 90° = 180°
Θ + 134° = 180° ( subtract 134° from both sides )
Θ = 46°
The answer is c becuse there’s only 2 cs and 3 of the others
Answer:
12.56
Step-by-step explanation:
Radius*2=Diameter
Circumference is pi*Diameter
Exactly what was your answer for a
Answer:24
Step-by-step explanation: divide 75 by 5 and subtract that from 75 (75-15) and then take that answer and divide it by 5 as well (60/5) and multiply that by 3 (12x3) and subtract that from 60 (60-36) to get 24
