My triangle solver says EF ≈ 7.5 ft.
_____
The law of cosines is usually used for this.
EF^2 = DE^2 +DF^2 -2*DE*DF*cos(D)
.. = 6^2 +11^2 -2*6*11*cos(40°)
.. ≈ 55.88
EF ≈ √55.88 ≈ 7.5 . . . ft
Answer:
A factor is a number that when its multiplied with another number, gives a product of a given number. Example: The factors of 21 are 7,3,1 and 21.

Answer:
Step-by-step explanation:
Example 7:
$2250 x 7.65% = $2250 x .0765 = $172.13
$172.13 is withheld for Social Security and Medicare.
Example 8:
$36,000 * 27% = $36,000 x .27= $9,270
$36,000 - $9,270 = $26,730
He makes $26,730 after deductions.
