Answer 1

Answer:

ad= 60/13

Step-by-step explanation:

given

ac=12cm

bc=13cm

in triangle abc

ab2+ac2=bc2    (pythagoras theorem)

ab2+(12)2=(13)2

ab2+144=169

ab2=169-144

ab2=25

ab=root 25

ab= 5

area of triangle abc = 1/2*b*h

b=12cm and h= 5

area of triangle = 1/2 *b*h

1/2*12*5

=30 cm   ---1

area of triangle abc = 1/2*b*h

1/2*ad*bc = 1/2 *ac*ab

1/2*ad*13=30 cm (from 1)

1/2*ad*13=30

ad=30*1/13*2

ad= 60/13
