What are trigonometry ratios?
Trigonometric ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.
various ratios are:-
- sin=perpendicular/hypoteneuse
- cos=base/hypotenuse
- tan=perpendicular/base (tan30°)=5/b
- cot=base/perpendicular
- sec=hypotenuse/base
- cosec= hypotenuse/perpendicular
The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as trigonometric.
CALCULATIONS:-
The angle of elevation is 70°
using the height and distance formula
cos∅ = base/hypotenuse
cos 70°= 0.454
cos∅ = base/hypotenuse
0.454 =14/hypotenuse
hypotenuse(length of ladder)= 14/0.454
length of ladder= 30.83 ft
