In δabc below, what is the measure of angle b? in particular, which option below gives an exact expression for m b and an approximation that is correct to the nearest tenth of a degree? answer choices are show in the pictures! !

sin^(-1)(3/4)=48.6

Step-by-step explanation:

Sin of an angle equals opposite cat./hip

Then,

Sin(b) = 3/4

So B = arcsin 3/4

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:
