Question

Please help me with this problem it is pair each of triangles are similar but not drawn to scale. Calculate any lettered lengths

Answer 1

b = 5.5m a = 6m

b = 17cm a = 80cm

Explanation:

The second triangle in the pair is a scaled-up version of the first triangle.

To find b in the first triangle you do 11/2 = 5.5m

To find a in the second triangle you do 3*2 = 6m

To find b in the third triangle you do 68/4 = 17cm

To find a in the fourth triangle you do 20*4 = 80cm
