Question

Use the diagram below to find the lengths of the missing sides. Figures in each diagram are similar.

X=1
X=5
X=4.5
X=15

Answer 1

a/15 =6/20
a = 15x6 /20 = 4.5
Using pythagoreas :
Xy= 7.5
And rq = 25

Answer 2

4.5

Explanation:

The two triangles are similar

so the equation is

`(a)/(6) = (15)/(20)`

`20a = 90`

`a = (90)/(20)`

`a = 4.5`
