Ответ:
y = 6.69 ft
Step-by-step explanation:
Given : A right angled triangle with perpendicular is y ft and hypotenuse is 15 ft.
We have to find the measure of y.
Consider the given triangle
Using trigonometric ratio,
Sine of angle is the ratio of perpendicular to its hypotenuse.
Thus,
For
We have perpendicular = y ft and hypotenuse = 15 ft.
Multiply both side by 15, we have,
Simplify, we have ,
y = 6.69
Thus, y = 6.69 ft
