Answer:

64 feet

Step-by-step explanation:

To find the height of the kite we use sin trigonometric ratio.

Let the height of the kite from the ground be x feet.

\therefore \: \sin 40 \degree =  \frac{x}{100}  \\  \\  \therefore \: 0.6427876097=  \frac{x}{100}  \\  \\ \therefore \: 0.6427876097 \times 100= x \\  \\  \therefore \:x = 64.29  \\  \\  \therefore \:x = 64 \: feet

Chico walks 3/5 mile to the library. Nikki walks 1/4 the distance that Chico walks to the library. How far does Nikki walk?
Effectus [21]
3/5 miles = 0.6 miles
0.6/4= 0.15 miles

Nikki walked 0.15 miles or 3/20 miles.

Multiply the bottom of the fractions together (4*5=20) and the tops (3*1=3) to get 3/20.
