Answer:

sinE = \frac{3}{5}

Step-by-step explanation:

To find sinE we require DF

Using Pythagoras' identity in the right triangle

DF² = EF² - DE² = 10² - 8² = 100 - 64 = 36 ( take square root of both sides )

DF = \sqrt{36} = 6

Then

sinE = \frac{opposite}{hypotenuse} = \frac{DF}{EF} = \frac{6}{10} = \frac{3}{5}

Karo-lina-s [1.5K]

Answer:

Percentage error is 0.0024 %

Step-by-step explanation:

Initial average distance between Earth and moon = 384467 km  

Distance measure by the scientist = 384476 km

Total variation in the distance calculation = 384476 – 384467 = 9 km.

Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.

Percentage error = ( 9 /  384467 ) × 100 = 0.0024 %
