Question

Express the length of the kite string in terms of trigonometric ratios. A) 70cos40° B) 70sin40° C) 40 sin70° D) 70 sin40°

Answer 1

Answer:

The length of the kite string in terms of trigonometric ratios, if we call it L, is $L=\frac{70}{sin(40\°)}ft$

Step-by-step explanation:

As we have to use the trigonometric ratios, and knowing that in a right triangle the relation

$hypotenuse*sin(angle)=opposite leg$

is valid. We call the hypotenuse as L, and we know the other two data (angle and opposite leg), so we have that

$L*sin(40\°)=70ft\Leftrightarrow L=\frac{70}{sin(40\°)}ft$

Then,

$L=\frac{70}{sin(40\°)}ft$

is the answer that we are looking for to solve the problem.
