Answer:

C^2=A^2+B^2

=11.87^2+18^2

= 140.90+324

= 464.9

C= square root of 464.9

= 21.56, the hypotenuse

Siny= 18/21.56

= 0.835

y =Sin^-1(0.835)

=56.62

Sinx= 11.87/21.56

=0.551

x =Sin^-1(0.551)

= 33.44

thats one way, i chose a longer way cuz i think its better to go through the steps

Step-by-step explanation:

Sin=opp/hyp

Cos=adj/hyp

Tan=opp/adj

you can use these to solve it other ways
