Question

Given that ACAB - ACED, lind the value of y to 1 dermal place
​

Answer 1

y = 15

Explanation:

The triangles CAB and CED are similar (Using the case AA), so we can write the following relations:

`(12)/(28) =(15)/(x)=(y)/(35)`

Using the first two fractions, we can find the value of x:

`(12)/(28) =(15)/(x)`

`12x = 28*15`

`12x = 504`

`x = 504/12 = 42`

Using the first and last fractions, we can find the value of y:

`(12)/(28) =(y)/(35)`

`28y = 12*35`

`28y = 420`

`y = 420/28 = 15`
