Answer: 41.81 °
Explanation:
For this question we know the opposite side of x and the hypotonuse , so we can use sin. Then you must write an equation: sin x = 4/6 .
Afterwards, you must multiply both sides of the equation with inverse sin so the equation will now look like: sin‾¹ * sin x = sin‾¹ (4 / 6)
The inverse sin cancels out the sin thats x, so: x = sin‾¹ (4/6)
Type sin‾¹ (4/6) in your calculator to get your angle value. Make sure your calculator is in degrees mode, by default calculators are set to radians( radians are another way to represent angles)
