Answer:
BC = 5
BA11
angle D = 27
Step-by-step explanation:
If the triangles are similar
ABC ≅ DEF
That means AB ≅ DE
BC ≅ EF
and CA ≅ FD
We want to find AB so it is equal to DE
BC = EF = 5
BA = AB = DE =11
We also know the angles are equal
A = D
B = E
C = F
Angle A = angle D = 27

Move variables to the left by adding their opposites to both sides. Eliminate the opposites.

Move constants to the right by adding their opposites to both sides. Eliminate the opposites.

Collect the like terms by subtracting their coefficients and numbers.

Calculate the sum or difference. Extract the negative sign from the expression. Add the numbers.

Divide both sides of the equation by 5 and calculate the quotient.

Compare diagonally to see if they the 2 numbers simplify.
Ex:
3 and 6 Simplify to 1 and 2 because they are both multiples of 3.
9 and 15 Simplify to 3 and 5 because they are both multiples of 3 as well.
