Answer:
The correct answer is option <em>B. AA</em>
<em></em>
Step-by-step explanation:
Given two triangle:
and 
.
The dimensions given in are:
We know that the sum of three angles in a triangle is equal to 
.
The dimensions given in are:
We know that the sum of three angles in a triangle is equal to .
Now, if we compare the angles of the two triangles:
So, by AA postulate (i.e. Angle - Angle) postulate, the two triangles are similar.
by <em>AA theorem.</em>
<em>So, correct answer is option B. AA </em>
Answer:
64.6 km/h
Step-by-step explanation:
18:14 = 18h 14'
1h = 60'
18h = 17h + 60'
18h14' = 17h + 60' ´14' = 17h 74'
then:
17h 74'
-17h 22'
= 0h 52'
the train travelled 56km at 52 minutes
56km/52minutes
1 hour = 60 minutes
52 minutes = 52/60 = 0.86667 hours
then:
56km/52minutes = 56km/0.86667hours
= 64.615 km/hours
The range is all positive values...
R{y | y>0}
Range > "Y" such that y is greater than 0
Answer:
A right triangle
Step-by-step explanation:
The answer is a right triangle because it has a right angle. A right angle is 90 degrees
Answer:
36
Step-by-step explanation:
Data provided in the question:
Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )
Standard deviation = 9 minutes ( ∵ number are repetitive 99 )
Now,
Standard error = ( Standard deviation ) ÷ √n
Here,
n is the sample size
Therefore,
on substituting the respective values, we get
1.5 = 9 ÷ √n
or
√n = 9 ÷ 1.5
or
√n = 6
or
n = 6² = 36
