Question

Trigonometry (ASAP) (Urgent) ​

Answer 1

Answer:

h = 1.403733341286

Step-by-step explanation:

17.

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

Then

$\cos \theta =\frac{l-h}{l}$

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
