How do I find Sin A .42 is A is an acute angle. And how do i enter that on a calculator?
If sin(A) = 0.42 then A = arcsin(0.42).On calculators, the arcsin key is usually reached by using another key before the sin key, and is shown as "sin to the power -1".Make sure that your calculator is set to degrees rather than radians (to check this, try sin(90). If the answer is 1 the calculator is in degree mode; if it is 0.8940 it is in radian mode.
