Answer:
D.130°
Step-by-step explanation:
An arc measure ia an angle an arc makes with the circle's centre and is proportional to the angle it subtends to the circumference, arc length.
-Given that AC and BC are diameters, then
since they are alternate angles.
![\angle AOB =\angle dOC=180\textdegree\\\\3x-70=x+10\\\\x=40\textdegree](https://tex.z-dn.net/?f=%5Cangle%20AOB%20%3D%5Cangle%20dOC%3D180%5Ctextdegree%5C%5C%5C%5C3x-70%3Dx%2B10%5C%5C%5C%5Cx%3D40%5Ctextdegree)
#Since angles on one side of a diameter sum up to 180°, mBC is calculated as:
![(3x-70)+m\angle BC=180\\\\M\angle BC=180+70-3\times 40\\\\=130\textdegree](https://tex.z-dn.net/?f=%283x-70%29%2Bm%5Cangle%20BC%3D180%5C%5C%5C%5CM%5Cangle%20BC%3D180%2B70-3%5Ctimes%2040%5C%5C%5C%5C%3D130%5Ctextdegree)
Hence, mBC=130°

1. The natural numbers are those that are used for counting. Natural numbers cannot be negative.
2. A whole number is a member of the set {0,1, 2, 3, …} - this set is the set of natural numbers with zero. Whole numbers cannot be negative.
3. Integers include whole numbers and negative whole numbers. Integers can be positive, negative, or zero.
4. Real numbers include:
- natural numbers;
- whole numbers;
- integers;
- rational numbers;
- irrational numbers.
Real Numbers can also be positive, negative or zero.
Consider number -1.2. It is negative, then options 1 and 2 are wrong. Also option 3 is false, because 1.2 is not natural number (cannot be used for counting), then -1.2 is not integer. Number -1.2 is real number.
Answer: correct choice is D.
