Answer:
Step-by-step explanation:
You are not correct. Find the angle by using the inverse button of whichever trig ratio you pick. I used tangent:
[tex]tan^{-1}(72/30)=67.38[/tex]
Answer:
67
Step-by-step explanation:
alert the unknown angle be x.
Using Trigonometric ratio,
sin x = 72 / 78
x = arcsin ( 72/78)
x = 67.38
x = 67
Therefore, the indicated angle is 67
