Answer 2

Answer:

mark as brainliest

Step-by-step explanation:

ABC is a right triangle, right angled at B, with AB= 3cm and BC=4cm. BD is drawn perpendicular to the hypotenuse AC. What is the length of BD if AC= 5cm? I can find only similar triangles side proportion theorem.

Method-1

AD=(AB)cosA

AD=3×cos(b2+c2−a22bc)

AD=3×cos(52+32−422×5×3)

AD=1.8

BD2=AB2−AD2

BD2=32−1.82

BD=2.4

Method-2

The height of the triangle BD is denoted by hb

The area of the given triangle is, A=123×4=6sq.units
