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
