Question

Abc=90°, Bm_|_AC, AN=18 cm, BC=24cm, BM=?cm

Answer 1

Answer:

14.4 cm

Step-by-step explanation:

AC = 30 cm using pythagoreas theorem

area of triangle = 1/2 ×b×h

                          =1/2 × 24 × 18

                          = 216 cm²

area of triangle = 1/2 ×b×h

                          = 1/2×30×h

                          = 15h

area = area

216 = 15h

h = 216/15

h = 14.4
