Question

in triangle ABC if angleB =90 and BD is perpendicular to AC if AB =3 cm BC =4 then find BD​

Answer 1

Answer:

5 cm

Step-by-step explanation:

B = 90 degrees

AB = 3 cm

BC = 4 cm

so,this is a right angle triangle

according to pythagoras theorem

(BD²) = (AB²) + (BC²)

(BD²) =  (3²) + (4²)

BD = √ 9+ 16

BD  = √25

BD  = 5 cm
