Question

find AE in a ∆ if AB is 10.5 cm
CD is 4 cm
and BC is 6cm​

Answer 1

Answer:

if both AE and CD are perpendicular to CB and AB respectively then

AE=7 cm

Step-by-step explanation:

in ΔABC, if both AE and CD are perpendicular to CB and AB respectively

then they can be considered as height

since it is the same triangle

ar(ABC)=ar(ABC)

1/2 x BC x AE= 1/2 x AB x CD

BC x AE= AB x CD

10.5 x 4 = 6 x AE

AE = 7 cm
