Drag each tile to the correct box. Arrange the angles in increasing order of their cosines.
inna [77]

Answer:

\frac{3\pi}{4}

Step-by-step explanation:

we are given different angles

we can see that each angles have different denominators

so, firstly we will find common denominators

denominators are 1 , 2,3,4,6

so, LCD will be 12

now, we will make denominator of all terms 12

\frac{3\pi}{4} =\frac{3\pi\times 3}{4\times 3}=\frac{9\pi}{12}

\pi =\frac{\pi\times 12}{1\times 12}=\frac{12\pi}{12}

\frac{7\pi}{6} =\frac{7\pi\times 2}{6\times 2}=\frac{14\pi}{12}

\frac{5\pi}{3} =\frac{5\pi\times 4}{3\times 4}=\frac{20\pi}{12}

\frac{7\pi}{4} =\frac{7\pi\times 3}{4\times 3}=\frac{21\pi}{12}

\frac{4\pi}{3} =\frac{4\pi\times 4}{3\times 4}=\frac{16\pi}{12}

\frac{3\pi}{2} =\frac{3\pi\times 6}{2\times 6}=\frac{18\pi}{12}

2\pi =\frac{2\pi\times 12}{1\times 12}=\frac{24\pi}{12}

we can see that denominators are same

so, we can arrange it according to numerators as

\frac{9\pi}{12}

we can replace values

and we get order as

\frac{3\pi}{4}

How do you solve for this ?
Iteru [2.4K]
G(x) is irrelevant in this so cross that out. First it's asking for f(4) so plug in 4 to the f(x) equation *f(x)= 4^2+1 = 17. then you square 17 so 17^2 is 289
