In right triangle DEF, it is known that Cos D = (12/13) and Cos F = (5/13). If FD = 39, then DE = ? Hint, draw the right triangl
AnnyKZ [126]

Answer:

The value of the line segment ED is 36.

Step-by-step explanation:

The hypotenuse represents the longest side in the right triangle. In this case, FD represents the hypotenuse as it is a multiple of 13. Based on the trigonometric relations described in the statements, we get the following relationships by definition of cosines:

\cos D = \frac{ED}{FD} (1)

\cos F = \frac{EF}{FD} (2)

If we know that \cos D = \frac{12}{13} and FD = 39, then the length of the line segment ED is:

ED = FD\cdot \cos D

ED = 39\cdot \left(\frac{12}{13} \right)

ED = 36

The value of the line segment ED is 36.

Wendy throws a dart at this square-shaped target:
Ostrovityanka [42]

Answer:

Hello! I hope I am correct! :)

Step-by-step explanation:

Let’s first calculate the black circle & the white space.

Since there is more white space than the black circle, we already know that the white space will have more probability.

These are the steps you need to do, in order to so love this problem:

1. Find the area of both, the white space and the black circle.

2. Divide both of them by the area of the square.

3. Do all these steps to find the probability/hitting.

Part A:

Black circle: ( π *1^2) / ( π 5^2) = 1/25 = .04 or 3.14% chance.

So we can tell it’s close to zero.

Part B: 1 - .04 = 0.96 or 97%

This is close to one.

(Remember I am not saying the exact, it’s a estimate)

Brainliest would be appreciated!

Hope this helps! :)
