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

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun
