4x = 28
28 divided by 4 = 7
x = 7
4•7=28 (TRUE STATEMENT)
The value of the length of the rhombus will be found as follows:
cos θ=adjacent /hypotenuse
θ=108/2=54°
adjacent = 9/2=4.5 inch
hypotenuse=length of the rhombus
thus
cos 54=9/x
x=4.5/cos 54
x=7.6558~8 inches
the answer is 8 inches
Answer:
18.=400%
Step-by-step explanation:
80/20 we get 4 then we multiple 4 ×100 we get 400 and we check the answer 400% ×20 =80
I would go with
G: 4 cm
Or
J: 8 cm
Let me know if you get it correct! :)
The answer would be D. The law of cosines.
