cos(220)= a/3

cos (22 0^{\circ}) = \frac{a}{3}

a = 3 cos (22 0^{\circ})

Decimal Notation

a = - 2.29813 \dots

Solution steps

cos (22 0^{\circ}) = \frac{a}{3}

Switch sides

\frac{a}{3} = cos (22 0^{\circ})

Multiply both sides by

3

\frac{a}{3} = cos (22 0^{\circ})

Multiply both sides by

3

\frac{3 a}{3} = 3 cos (22 0^{\circ})

Simplify

a = 3 cos (22 0^{\circ})

a = 3 cos (22 0^{\circ})

c, 1 f = 3 cos (x) - 4 sec (x) + 3

y = cos^{215} (0) - sin^{215} (0)

sin (6 0^{\circ}) = (\frac{x}{81})

d = 7.2 sec (\cdot sin (3 0^{\circ} - 2 0^{\circ}))

\frac{a}{sin ( 4 4 ^{\circ} )} = \frac{9}{sin ( 6 6 ^{\circ} )}
