Question

15. The figure shows two triangles ABC and ADE. 2 cm В. x cm 3 cm 3.5 cm A A E 6 cm с 5 cm () Determine if AADE is an enlargement of ДАВС (ii) Find the value of cos 0. (iii) Hence, find the value of x.​

Answer 1

Step-by-step explanation:

In the given figure,

△ABC∼△ADE

AE=2 cm,EC=3 cm,DE=1.6 cm

We know that

AC

AE

=

BC

DE

AE+EC

AE

=

BC

DE

2+3

2

=

BC

1.6
