Question

Trigonometry (ASAP) (Urgent) ​

Answer 1

h = 1.403733341286

Explanation:

17.

the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.

Then

`\cos \theta =(l-h)/(l)`

Then

`l\cos \theta =l-h`

Then

`h=l-l\cos \theta`

18.

For l = 6 and θ = 40 :

`h=l-l\cos \theta`

= 6-6cos(40)

= 1.403733341286
