sin(x)=(sin(45))/(1.3)

sin (x) = \frac{sin ( 4 5 ^{\circ} )}{1.3}

x = 0.57511 \dots + 36 0^{\circ} n, x = 18 0^{\circ} - 0.57511 \dots + 36 0^{\circ} n

Radians

x = 0.57511 \dots + 2 πn, x = π - 0.57511 \dots + 2 πn

Solution steps

sin (x) = \frac{sin ( 4 5 ^{\circ} )}{1.3}

sin (4 5^{\circ}) = \frac{2}{2}

sin (4 5^{\circ})

Use the following trivial identity:

sin (4 5^{\circ}) = \frac{2}{2}

sin (4 5^{\circ})

sin (x)

= \frac{2}{2}

= \frac{2}{2}

sin (x) = \frac{\frac{2}{2}}{1.3}

Simplify

\frac{\frac{2}{2}}{1.3} : \frac{2}{2.6}

\frac{\frac{2}{2}}{1.3}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{2}{2 \cdot 1.3}

Multiply the numbers:

2 \cdot 1.3 = 2.6

= \frac{2}{2.6}

Apply trig inverse properties

sin (x) = \frac{2}{2.6}

General solutions for

sin (x) = \frac{2}{2.6}

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

x = arcsin (\frac{2}{2.6}) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (\frac{2}{2.6}) + 36 0^{\circ} n

x = arcsin (\frac{2}{2.6}) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (\frac{2}{2.6}) + 36 0^{\circ} n

Show solutions in decimal form

x = 0.57511 \dots + 36 0^{\circ} n, x = 18 0^{\circ} - 0.57511 \dots + 36 0^{\circ} n
