Question

ABC is a triangle with BC=12cm and AC = 8 cm . AX and BY are the perpendiculars on BC and AC respectively. If AX=7cm , find BY​

Answer 1

Answer:

10.5 cm

Step-by-step explanation:

area of 1st triangle=area of 2nd triangle

(1/2)*b*h=(1/2)*b*h

(If 1/2 will cancel each other)

b*h=b*h

12*7=8*h

84/8=h

h=10.5cm

Answer 2

Answer:

10.5

12× 7=8×h

84=8h

h=84/8

h= 10.5ans
