Find sin θ if cos θ = 4/7 and θ in quadrant IV.

sinΘ = -

Step-by-step explanation:

Using the trigonometric identity

sin²Θ + cos²Θ = 1, thus

sinΘ = ±

Since Θ is in the fourth quadrant then sinΘ < 0

Given

cosΘ = , then

sinΘ = - = - = - = -

false

step-by-step explanation:

the meaning of changing is to edit or make something different.

but transmitting means cause (something) to pass on from one place or person to another.

there 2 different things

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
