Answer:
Angle bisector
Step-by-step explanation:
Find the measure of the angle COA. By angle addition postulate,
From the diagram,
then
Find the measure of the angle BOA. By angle addition postulate,
From the diagram,
then
Find the measure of the angle COB. By angle addition postulate,
From the diagram,
then
This means, the measures of angles COB and BOA are the same and are equal half the measure of angle COA, so angles COB and BOA are congruent. This means, the ray OB is the angle bisector of angle COA

Answer:
Step-by-step explanation:
Assuming a normal distribution for the distribution of the points scored by students in the exam, the formula for normal distribution is expressed as
z = (x - u)/s
Where
x = points scored by students
u = mean score
s = standard deviation
From the information given,
u = 70 points
s = 10.
We want to find the probability of students scored between 40 points and 100 points. It is expressed as
P(40 lesser than x lesser than or equal to 100)
For x = 40,
z = (40 - 70)/10 =-3.0
Looking at the normal distribution table, the corresponding z score is 0.0135
For x = 100,
z = (100 - 70)/10 =3.0
Looking at the normal distribution table, the corresponding z score is 0.99865
P(40 lesser than x lesser than or equal to 100) = 0.99865 - 0.0135 = 0.98515
The percentage of students scored between 40 points and 100 points will be 0.986 × 100 = 98.4%
Answer and Step-by-step explanation:
This problem requires the use of trigonometric functions, specifically the tangent trig function.
Plug in the values.
Multiply by x to both sides, then divide by tan(40) to both sides.
Now, plug this into a calculator and rounded to the nearest whole number (foot).
x = 9534.0287
x = 9534 ft.
The answer is 9534 ft., the last option.

49 multiply by 14% is 6.86
42.14 + 6.86= 59
