Answer:
Option B is correct 65°
Step-by-step explanation:
Apply the trigonometric identity sine
Do not forget to convert your calculator into degree form if it is set to radian.
Alright since you haven't studied trigonometry forget what i said here xD
The table given are the ratios of the respective angles 55, 65, 75.
First we need the adjacent side of the triangle. We have the opposite side of the triangle which is 6.1 and the hypotenuse which is 6.7 we use Pythagoras theorem
So now lets compare the ratios in table
Firstly
so we can see that all these values 0.413, 0.91, 2.2 correspond to the angle 65° so Option B is correct
