<span>So we want to know what is the lenght of the sides of the board that has an area of A=144 in^2. Well, we know that the area of a square is A=a^2 where a is the side of a square. So the length of the side is square root of the area: sqrt(144)= 12. So the length of the game board is 12 inches.</span>
Displacement(d)=0.2m
Time taken(t)= 30 s(1min=60 s)
Velocity (v)=?
We know that,
Velocity (v) = d/t
=0.0067
Answer:
D. 60°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relationship of interest is ...
Sin = Opposite/Hypotenuse
sin(M) = ON/OM = 4(√3)/8 = (√3)/2
M = sin⁻¹((√3)/2) = 60°
0.25=25/100=1/4. 1/4×84=84/4=21. The answer is 21
