Please help, help. Please

Below.

Step-by-step explanation:

AE || DF

AE ≅ DF

AB ≅ CD          Reason: Given

AC ≅ BD            Reason: AB ≅ CD (given) and BC is common to both lines.

m < EAC = m< FDB   Reason:  Interior alternate angles.

So Triangle EAC ≅ triangle FDB by SAS.

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.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
