cos(A)= 8/17

cos (A) = \frac{8}{17}

A = 1.08083 \dots + 2 πn, A = 2 π - 1.08083 \dots + 2 πn

Degrees

A = 61.92751 \dots^{\circ} + 36 0^{\circ} n, A = 298.07248 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (A) = \frac{8}{17}

Apply trig inverse properties

cos (A) = \frac{8}{17}

General solutions for

cos (A) = \frac{8}{17}

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

A = arccos (\frac{8}{17}) + 2 πn, A = 2 π - arccos (\frac{8}{17}) + 2 πn

A = arccos (\frac{8}{17}) + 2 πn, A = 2 π - arccos (\frac{8}{17}) + 2 πn

Show solutions in decimal form

A = 1.08083 \dots + 2 πn, A = 2 π - 1.08083 \dots + 2 πn

sec (θ) = \frac{6}{- 5}, sec (- θ)

cos (π z) = 0

sin (x) \cdot cos (x) - 3 cos (x) = 0

9.8 \cdot sin (α) - 0.2 \cdot 9.8 \cdot cos (α) = 0.47

- sin (x) + 3 cos (x) = 0
