<u>Trigonometric Ratios</u>
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:
Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:
Calculating the inverse sine function:
Let the ladder length be L, then
sin 70 = 20/L, L = 20/sin70 = 21.3 feet
the length of ladder is 21.3 feet
Answer:
3(x) – 3(9)
Step-by-step explanation:
3(x-9)
Distribute the 3 to each term in the parentheses
3*x -3*9
3x -27
