3 3/4 x 1 1/2 = 15/4 x 3/2 = 45/8 = 5.625
Answer: you will use the cosine rule
Step-by-step explanation:
x^2=11^2+8^2-2(11)(8)xcos(16)
x^2=185-169.18
x^2=15.8
Take square root
x=3.96 or 4
35+35+35+35+35+35+35+35+35+35+35+35
Or
35×12
=420
8/10 can be simplified to 4/5 by dividing the top and bottom by 2. That is the simplest form because you cannot divide it any further.
