Answer:
B) 9
Step-by-step explanation:
Because there's a square between the 2 angles, that means these angles are complementary (angles that add up to 90°). So:
5x - 9 + 6x = 90
11x - 9 = 90
11x = 90 + 9
11x = 99
x = 9
Let n = total boxes (5)
Probability (p) = 1 out of 4 = 1/4 = 0.25
Probability she wins at most 1 out of 5 is p(x <=1) Which is also = p (x =0) + p(x=1)
Probability of not winning would be 0.75 ( 1-0.25)
No prizes in 5 boxes = 0.75^5
1 prize in 5 boxes = 5 x 0.25 x 0.75^4
Total probability = 0.75^5 + 5 x 0.25 x 0.75^4 = 0.63
sum of interior angle =n-2(180)
n is the number angles
5-2(180)
3(180)
=540
x=102+116+123+88=429
540-429=111
x=111
Answer:
![\bar {AQ} =\bar {QB}](https://tex.z-dn.net/?f=%5Cbar%20%7BAQ%7D%20%3D%5Cbar%20%7BQB%7D)
Step-by-step explanation:
Since line L passes through the center of the circle and it is perpendicular to chord AB, it bisects chord AB.
This means that L is the locus of points equidistant from A and B.
This also means that Q is the midpoint of AB.
Hence the correct answer is ![\bar {AQ} =\bar {QB}](https://tex.z-dn.net/?f=%5Cbar%20%7BAQ%7D%20%3D%5Cbar%20%7BQB%7D)
