Given
Angle = Ф = 24 degree
Length of long side reaches to = hypotenuse = 30 inch
To find :
The length of perpendicular = ?
As we know that :
Sin Ф = Perpendicular / Hypotenuse
Sin 24 = perpendicular / 30
0.4067 =perpendicular / 30
perpendicular = 30 / 0.4067
perpendicular = 73.76 inch
So the correct answer is option 3) 73.76 inch
Hope this answer helps you
