Answer:
Option (4)
Step-by-step explanation:
If two chords intersect outside the circle, angle formed between the chords will be half of the sum of measures of intercepted arcs.
From the given picture,
95° = 
190 = 135 + 
= 55°
Therefore, option (4) will be the correct option.
Cosine rule: a^2<span> = b^</span>2<span> + c^</span>2<span> - 2bc </span>cos<span> A
-> a^2 > b^2 + c^2 - 2bca
-> abc > (b^2 + c^2 - a^2) /2</span>
bro use a photo math...................
The answer to that is B it’s 60
1/6*1/6*1/6*1/6 = 1/1296 = 0.078% probability of ANY 4-letter sequence (including qqqq)
1000/1296 is less than 1.
Expected number of times qqqq (or any given 4-letter sequence) will appear in 1000 letters is 0.
