Question

find an obtuse angle whose sine is 0.52

Answer 1

Unless instructed otherwise, use a calculator to find the acute angle, then subtract it from 180 degrees.

------

For sin(A) = 0.52

Acute angle =~ 31.33 degs

Obtuse angle = 180 - 31.33 = 148.67 degs

Answer 2

Answer:

for sinA =0.52

acute angle =31.33 degs

obtuse angle =180-31.33=148.67 degs

hope the answer is 148.67 degs
