I hope it's clear

option b is the correct option

Answer 2

Answer:

option {b}is correct

DE=12cm,∠F=100degree

Step-by-step explanation:

ΔABC∼ΔDFE

AB/DF = AC/DE = BC/FE

5/7.5 = 8/DE = BC/FE

DE = 8×7.5/5 = 12cm

NOW,

     ∠A = ∠D = 30degree

∠B = ∠F = 180degree - 30degree - 50degree

∠C = ∠E = 50degree
