Respuesta :
Angle θ that the ladder makes with the ground is given by sin ⁻¹ (y/5)
Given,
height of ladder = 5 foot
distance between top of wall and ground = y
As it forms the right-angled triangle so,
θ is given by sin,
As we know
sin θ = Altitude / hypotenous
we are given altitude = y,
hypotenous = 5 foot
sin θ = y / 5
θ = sin ⁻¹ (y/5)
What is sine θ?
In a Right-angled triangle, the sine function or sine theta is defined as the ratio of the opposite side to the hypotenuse of the triangle. In a triangle, the Sine rule helps to relate the sides and angles of the triangle with its circumradius(R).
The sine of an angle of a right-angled triangle is the ratio of its altitude (that is opposite to the angle) to the hypotenuse.
