Answer:
AB = 5.2
AC = 5.2
m∠3 = 30 degrees
, m∠4 = 30 degrees
Step-by-step explanation:
Triangle ABO and ACO are both 30 60 90 triangles and are equal
Therefore If we have two sides then we can figure out the last side

Answer:
x = 5.25
Step-by-step explanation:
35 + 7 = 42
6x + 2x = 8x
42 / 8x = 5.25
If I wrote it right, it should be 14.53
Answer:
0.3960
Step-by-step explanation:
X - no of questions answered correct is binomial since each question is independent of the other and there are two outcomes
p = Prob of any one question right = 0.2 (1/5)
n = 44
Normal approximation would be mean = np = 8.8 and Variance = npq = 7.04
Std dev = 
X is N(8.8,2.6534)
Or Z = 
Since we approximate discrete to continuous continuity correction is to be applied
means x≥9.5
P(X≥9.5) = 0.3960
