Using a calculator determine each to 1 decimal place sinalph

Using a calculator, determine each to 1 decimal place: sin(alpha) = 0.195946 implies alpha tan(beta) = 1.75319 implies beta sec(theta) = 1.67329 implies theta

Solution

1 ) Given that

sin() = 0.195946

    = sin^-1(0.195946)

= 11.3

2 ) tan() = 1.75319

   = tan^-1(1.75319)

= 60.3

3 ) sec() = 1.67329

    = sec^-1(1.67329)

   = 59.1
