Answer is d=2 1/3
Because find area of a triangle =1/2×b×h
U will get 7/3
Cos x = 15÷17
because cos is adjacent side over hypotenuse.
To find the lowest common denominator you need to know the factors of 5 and 11.
So make two lists:
5, 10, 15, 20, 25, 30, and so on.
11, 22, 33, 44, 55, 66, and so on.
Keep doing that until you find the lowest common number in the lists. The LCD will be 55.
