Question

Please could I have some help with this question? Thanks ​

Answer 1

Answer: 270

Explanation:

1) Find DE

1 : 6

17 : x

Cross multiply

x = 17 * 6

x = 102

DE = 102

2) Compare the two triangles

1st (ABC)

side = 45

base = 17

2nd (ADE)

side = x

base = 102

`(x)/(45) = (102)/(17)`

Cross multiply

17x = 102 x 45

17x = 4590

x = 4590/17

x = 270

AD = 270
