In triangle DEF, DK is the angle bisector of angle EDF. If EK=2, FK=5, and DF=10, what is the length of DE?

fiasKO [112]

Answer:

4 units

Step-by-step explanation:

In triangle DEF, DK is the angle bisector of angle EDF.

<u>Angle bisector theorem</u> states that if a ray bisects an angle of a triangle, then it divides the opposite side into segments that are proportional to the other two sides.

Hence,

$\dfrac{DE}{DF}=\dfrac{EK}{KF}$

Thus,

$\dfrac{DE}{10}=\dfrac{2}{5}\\ \\5DE=2\cdot 10\\ \\5DE=20\\ \\DE=4$

For every 140 feet that kelly rides on her bicycle, the wheels turn 20 times. About how many times do the wheels turn in 5 miles

o-na [289]

Answer:

Approximately 3771 times

Step-by-step explanation:

Let x be the number of times the wheels turn in 5 miles.

Given that, 1mile = 5,280ft

Thus, 5 miles=5 × 5,280ft=26400ft

From the question ,we can deduce the following ratios :

140 ft : 20 mins

26400ft : x

Cross multiply;

$\implies \: x \times 140 = 26400 \times 20$

$\implies140x =528000$

Divide through by 140.

$\implies \frac{140x}{140} = \frac{528000}{140}$

$\implies x=3771.43$
