Given that abc and def are similar find fd

FD = 8

Step-by-step explanation:

since they are similar triangle .use these ratios to find FD

AB/DE = AC/FD

now substitute the values

6/x-3 = 12/x+1

do cross multiplication

12(x-3) = 6(x+1)

12x - 36 = 6x + 6

12x - 6x = 6 + 36

6x = 42

x = 42/6

x = 7

now substitute x

FD = x + 1

=7 + 1

=8

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
