Question

Can somebody help me please

Answer 1

x = 5

Explanation:

The inner and outer triangles are similar by the AA postulate then the ratios of corresponding sides are in proportion, that is

`(x)/(2)` =
`(6+4)/(4)` =
`(10)/(4)` = 2.5 ( multiply both sides by 2 to clear the fraction )

x = 5
