Answer:

Given that

sinθ = 0.8660

⇒ sinθ = 0.8660 = √3/2

⇒ θ = sin⁻¹(√3/2)

⇒ θ = 60°

Answer:

Step-by-step explanation:

Given

Sin\theta =0.8660

And hypotenuse =0.25

And we know

sin\theta =\frac{Perpendicular}{Hypotenuse}

by simple observation

we know sin(30)=0.5

it means that \theta is greater than 45

sin(45)=0.7071

i.e. \thetais greater than 45

for sin(60)=\frac{\sqrt{3}}{2}=0.8660

thus \theta =60^{\circ}

Art [367]

f(x)=4x^3 - 6x^2 + 2x - 5

f(-2)


Replace X with -2:

4(-2)^3 - 6(-2)^2 + 2(-2) - 5 =

Calulate the powers:

4(-8) - 6(4) +(-4) -5=

Multiply:

-32 - 24 -4 -5=

Subtract
