Given 7 cos θ -3 = 2;0° <θ < 180 ° Determine sin θ

Given: 5sin2(θ) - 6sin(θ) - 8 = 0 where 180 < θ < 270. Solution: Let x = sin(θ). Substituting x to the equation: -> 5sin2(θ) - 6sin(θ) - 8 = 0.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
