Sagot :
Answer:
- B. the direct method
- B. 30°
- C. eqaully likes events
Step-by-step explanation:
1. In direct method we have to assume the hypothesis as we have assumed the hypothesis "Let OM be the perpendicular to chord AB" in this case hence the option is B
2. Let the angle of triangle be 2x , 3x , & 7x
By angle sum property:-
2x+3x+7x=180
∘
⇒12x=180
∘
⇒x=15
2x=2×15=30
∘
3x=3×15=75
∘
7x=7×15=105
∘
Smallest Angle=30
30 ∘
3. Equally Likely Events. Equally likely events are events that have the same theoretical probability (or likelihood) of occurring.

The perpendicular from centre of a circle to the chord, bisects the chord." The proof started from assumption "Let OM be the perpendicular to chord AB". This method of proof is
- A. The proof by contradiction
- B. The Direct method.
- C. Induction method.
- D. The proof by contrapositive method
The angles of a triangle are in the ratio 2:3:7. The measure of the smallest angle is:
- A. 90°
- B. 30°
- C. 45°
- D. 60°
If the events have the same theoretical probability of happening, then they are called
- A. Mutually exclusive events
- B. Mutually exhaustive events
- C. Equally likely events
- D. Impossible events
