1sin(30)=1.7sin(θ)

Solution

1 sin (3 0^{\circ}) = 1.7 sin (θ)

Solution

θ = 0.29853 \dots + 36 0^{\circ} n, θ = 18 0^{\circ} - 0.29853 \dots + 36 0^{\circ} n

Radians

θ = 0.29853 \dots + 2 πn, θ = π - 0.29853 \dots + 2 πn

Solution steps

1 \cdot sin (3 0^{\circ}) = 1.7 sin (θ)

sin (3 0^{\circ}) = \frac{1}{2}

sin (3 0^{\circ})

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

sin (3 0^{\circ})

sin (x)

= \frac{1}{2}

= \frac{1}{2}

1 \cdot \frac{1}{2} = 1.7 sin (θ)

Switch sides

1.7 sin (θ) = 1 \cdot \frac{1}{2}

Multiply both sides by

10

1.7 sin (θ) = 1 \cdot \frac{1}{2}

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere is one digit to the right of the decimal point, therefore multiply by

10

1.7 sin (θ) \cdot 10 = 1 \cdot \frac{1}{2} \cdot 10

Refine

17 sin (θ) = 5

17 sin (θ) = 5

Divide both sides by

17

17 sin (θ) = 5

Divide both sides by

17

\frac{17 sin ( θ )}{17} = \frac{5}{17}

Simplify

sin (θ) = \frac{5}{17}

sin (θ) = \frac{5}{17}

Apply trig inverse properties

sin (θ) = \frac{5}{17}

General solutions for

sin (θ) = \frac{5}{17}

sin (x) = a \Rightarrow x = arcsin (a) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (a) + 36 0^{\circ} n

θ = arcsin (\frac{5}{17}) + 36 0^{\circ} n, θ = 18 0^{\circ} - arcsin (\frac{5}{17}) + 36 0^{\circ} n

θ = arcsin (\frac{5}{17}) + 36 0^{\circ} n, θ = 18 0^{\circ} - arcsin (\frac{5}{17}) + 36 0^{\circ} n

Show solutions in decimal form

θ = 0.29853 \dots + 36 0^{\circ} n, θ = 18 0^{\circ} - 0.29853 \dots + 36 0^{\circ} n
