Question

PLEASE HELP LIKE NOW IM TIMED.. WILL GIVE BRAINLIEST!!! In the figure, ΔABC ~ ΔDEF. Solve for x. Triangles ABC and DEF. Angles B and E are congruent and measure 39 degrees. AB measures 20. BC measures 24. EF measures 6. DE measures x.
x = 5
x = 12
x = 4
x = 7.2

Answer 1

5 would be the answer, based on my calculations. maybe im too late for a brainliest...

Answer 2

Use CPCTC
Congruent Parts of a Congruent Triangle are Congruent

∠B ≅ ∠E
AB ≅ DE
BC ≅ EF

AB = 20
BC = 24
EF = 6
DE = x

20/24 = x/6

Solve for x, cross multiply

24(x) = 20(6)
24x = 120
24x/24 = 120/24
x = 120/24
x = 5

x = 5, or A is your answer

hope this helps
