cos(θ)=(800cos(70))/(425)

cos (θ) = \frac{800 cos ( 7 0 ^{\circ} )}{425}

θ = 0.87133 \dots + 36 0^{\circ} n, θ = 36 0^{\circ} - 0.87133 \dots + 36 0^{\circ} n

Solution steps

cos (θ) = \frac{800 cos ( 7 0 ^{\circ} )}{425}

Cancel the common factor:

25

cos (θ) = \frac{32 cos ( 7 0 ^{\circ} )}{17}

Apply trig inverse properties

θ = arccos (\frac{32 cos ( 7 0 ^{\circ} )}{17}) + 36 0^{\circ} n, θ = 36 0^{\circ} - arccos (\frac{32 cos ( 7 0 ^{\circ} )}{17}) + 36 0^{\circ} n

Show solutions in decimal form

θ = 0.87133 \dots + 36 0^{\circ} n, θ = 36 0^{\circ} - 0.87133 \dots + 36 0^{\circ} n

csc^{(2)} (x) - cot (x) = 2, 0 <, x < 360

2 sin (x) + \frac{3}{4} = \frac{3}{2}

sin (u) - 2 sin (u) cos (u) = 0

20 = 27 sin (x) - 1.5 cos (x)

- 3 sin (θ) = 0
