Answer:
The value of height does the ladder reach on the building = 21 ft
Explanation:
length of the ladder = 22 ft
Angle between the ground and the ladder = 70°
Now we have to calculate ( h ).
From the triangle ABC , [tex]\sin \theta[/tex] = [tex]\frac{h}{22}[/tex]
⇒ h = [tex]\sin \theta[/tex] × 22
Put the value of [tex]\theta[/tex] = 70° we get,
⇒ h = [tex]\sin[/tex] 70° × 22
⇒ h = 21 ft
This is the value of height does the ladder reach on the building.
