Question

hi❤❤❤

need help!!......​

Answer 1

Answer:

FIG(i)

by basic proportionality theorm

AD/DB=AB/EC

BY SUBSTITUTING VALUES

1.5/3=1/EC

X = 2

FIG(ii)

AD/DB=AE/EC

1.8/5.4=AD/7.2

AD=2.4

Answer 2

Step-by-step explanation:

HEY MATE...

WE CAN SOLVE THESE TYPE OF QUESTIONS BY USING EQUAL SIDE ANGLE RATIO..

$\huge \star \frac{ad}{db} = \frac{1.5}{3} = \frac{1}{2} = \frac{ae}{ec} = \frac{1}{2} \\ \huge \star ec = 2ae = 2 \: cm.$

$\huge\longrightarrow \: \frac{ae}{ec} = \frac{1.8}{5.4} = \frac{1}{3} = \frac{ad}{db} \\ \huge \longrightarrow \: ad = \frac{db}{3} = \frac{7.2}{3} = 2.4 \: cm$

$\huge\longrightarrow \: \frac{ae}{ec} = \frac{1.8}{5.4} = \frac{1}{3} = \frac{ad}{db}$
