They will be closer by ten hours but farther by ten as more hours pass by. So you forgot a starting distance of where it starts. If this is needed to be answered specifically, you'll need more information to support answers. Now what I told you is the straying answer.

10.) Kelly is flying a kite to which the angle of elevation is
jarptica [38.1K]

Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

  • l = 65m
  • θ = 70°

As you can see, there has been made a right angle triangle. So:

sin70 =  \frac{h}{l}  \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.

Conversion. Write a reduced fraction notation for 0.56.
____ [38]

Answer:

Reduced fraction: 14/25

Step-by-step explanation:

To write 0.56 in terms of fractions we need to multiply and divide the number by 100:

(0.56 * 100)/100 = 56/100. Then we simplify the fraction by dividing the numerator and denominator by the common factor 2 as many times as possible:

56/100 = 28/50 = 14/25

The fraction 14/25 cannot be more simplified

#3) since angle ABC is 115 degrees, to find EBC you simply have to subtract 115 from 90 and the answer is 25 degrees. 
#4)DGJ would be 30 degrees because you take 70 minus 40.
#5) a 90 degree angle.
