If cscθ = 1 1/4, then cosθ = .
±3/4
±4/5
±3/5
±1 3/2

±3/5.

Step-by-step explanation:

sinθ = 1/ csc θ

= 1 / 1 1/4

= 1 / 5/4

= 4/5.

Here we have a 3-4-5 right triangle with θ opposite the longest leg.

So cos θ = 3/5.

Also if θ is in the second quadrant  the cosθ = -3/5.

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
