It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)
I'm like girl do you have plans. Can't keep my heart in your hands. She kicked me out I'm like vro.
Given:
Two planks are each 1.5 m long.
One plank is 2.5m long.
To find:
The total length of all the three planks.
Solution:
Two planks are each 1.5 m long. So,
First plank = 1.5 m
Second plank = 1.5 m
One plank is 2.5m long. So,
Third plank = 2.5 m
Now, the total length of all the three planks is



Therefore, the total length of all the three planks is 5.5 m.
