The inclination angle is 10°
Step-by-step explanation:
The given scenario forms a right angled triangle where the length of ramp is hypotenuse and the rise of ramp is the perpendicular
Given
H = 4.2m
P = 0.7m
We have to use the trigonometric ratios to find the angle. The ratio that has to be used should involve both perpendicular and hypotenuse
Let x be the angle
then
[tex]sin\ x = \frac{P}{H}\\sin\ x = \frac{0.7}{4.2}\\sin\ x = 0.1666\\x = sin^{-1} (1.666)\\x = 9.59 => 10[/tex]
Hence,
The inclination angle is 10°
