Find the acute angle in radians?

Sin ø = 0.2
Cos ø = 0.2
Tan ø = 1.7

Ø = theta. I don t have the proper symbol

When sin θ = 0.2 :
θ = sin⁻¹ 0.2
θ = 0.2014 rad (to 4 sig. fig.)


When Cos θ = 0.2 :
θ = cos⁻¹ 0.2
θ = 1.369 rad (to 4 sig. fig.)


When tan θ = 1.7 :
θ = tan⁻¹ 1.7
θ = 1.039 rad (to 4 sig. fig.)

Use a calculator. Make sure it is set to radians:

sinθ = 0.2 ----> θ = sin⁻¹(0.2) = 0.20135792079
cosθ = 0.2 ----> θ = cos⁻¹(0.2) = 1.3694384060
tanθ = 1.7 ----> θ = tan⁻¹(1.7) = 1.0390722595

Sin(θ) = 0.2

θ = 0.2013579208 rad

Cos(θ) = 0.2

θ = 1.369438406 rad

Tan(θ) = 1.7

θ = 1.03907226 rad
