Answer:
∠3 = 18°
∠4 = 144°
∠2 = 36°
∠1 = 72°
Step-by-step explanation:
From the concept of alternate interior angles,
∠3 = 18°
Since the diagonal divides the rectangle into 4 parts with 2 of the rectangles being similar.
Then, the triangle with ∠3 & ∠4 is an Isosceles triangle and as such;
∠4 = 180 - 2(∠3)
∠4 = 180 - 2(18)
∠4 = 180 - 36
∠4 = 144°
∠2 = 180 - ∠4 (because sum of angles on a straight line is 180°)
∠2 = 180 - 144
∠2 = 36°
Like it was done for angle ∠4 above;
∠1 = (180 - 36)/2
∠1 = 144/2
∠1 = 72°
Answer:
ok so the earth radius is 1534mi so if that is the radius than the area is 7.39×10^6so then you divide that into 3 pieces so each piece would be 2,463,333.3333 the nearest million would be 2,000,000
Step-by-step explanation:
it would be 66 cause you know it
The estimated standard error for the sample is 6
Given,
Sample size, n = 36
Sample variance,
= 1296
Standard deviation, s = √1296
= 36
Standard error, SE = 
= 
= 
= 6
Concept
- Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
- Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by '
'
- Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’

Answer:
1/3
Step-by-step explanation:
Anything under 4 has a 4/6 chance, so whats left is 2/6, which is equal to 1/3.
