Use the given information a calculator to find 𝜃, to the nearest tenth of a degree, if 𝜃 is between 0° and 360°. sin 𝜃 = 0.4247 with 𝜃 in QII

Question

Can you explain what to enter into the calculator because I am confused.

Answer 1

sinx = 0.4247

x = 25.132 degrees in quadrant I, or 154.868 degrees

for quadrant II,

the angle = 154.9 rounded to one decimal

use a calculator with inverse trig functions

punch in .4247, the hit "shift" then sin

most calculators have a "shift" key

or go to Desmos online's scientific calculator, punch "func", then "sin-1", then put in .4247 and on the right upper side come up the answer 25.13167587

round it off to 25.1

subtract it from 180

to get 180-25.1= 154.9
