Asap! algebra 2 given sin(−θ)=1/5 and tanθ=6√/12 what is the value of cosθ ? a). 6/√60 b). −26/√5 c). −6/√60 d). 26/√5

First, recall that

So if , then .

Second,

We know that and , which means we should also have .

Third,

but as we've already shown, we need to have , so we pick the negative root.

Finally,

Unfortunately, none of the given answers match, so perhaps I've misunderstood one of the given conditions... In any case, this answer should tell you everything you need to know to find the right solution from the given options.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
