A simpler form of this expression would be 19y-9
Answer:
2 sqrt(19)
Step-by-step explanation:
We know that the angle between the two hands
360 /12 *2 = 60 degrees
We divide by 12 because there are 12 number and multiply by 2 because there are 2 number between 10 and 12
This is a triangle where we know 2 sides and the angle between them.
We can use the law of cosines to determine the third side
c^2 = a^2 + b^2 -2abcosC
Where C is the angle between sides a and b
a =4 and b = 10 C = 60 and we are looking for side c
c^2 = 4^2 + 10^2 -2*4*10 cos60
c^2 =16+100 - 80cos 60
c^2 = 76
Take the square root of each side
sqrt(c^2) = sqrt(76)
c = sqrt(76)
c =sqrt(4) sqrt(19)
c =2 sqrt(19)
There are 4 per row.
12 divided by 3 = 4.
Answer:
First angle is 45 and the second angle is 60
Step-by-step explanation:
150 + 105 = 255
360 - 255 = 105
the ratio is 3:4 I add the ratio so 7
105 / 7 = 15
The first angle with the ratio of 3 is 15 x 3 = 45
The second angle with the ratio of 4 is 4 x 15 = 60
