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.

Maeve’s family recipe for macaroni and cheese makes 4 servings of 310 calories each. Maeve decided to make 1 1/2 times the amoun

ser-zykov [4K]

Answer:

1,860 calories

Step-by-step explanation:

You start with 4 servings of macaroni and cheese with 310 calories per serving. She made 1 1/2 times more of the 4 servings. 1 1/2 as a decimal is 1.5, and 1.5 times 4 is 6. With 310 calories per serving you get the problem 6 x 310 which equals 1,860. Therefore, there are 1,860 calories in Maeve's mac n' cheese
