Question

Find the value of x. The diagram is not to scale

Answer 1

Answer:B-70

Explanation:

from the figure, In
`\triangle ABC\ \text{and}\ \triangle ADE`

`\Rightarrow (45)/(45)=(24)/(24)\\\Rightarrow (1)/(1)=(1)/(1)`

`\therefore \text{two triangles are similar}`

Thus we can write

`\Rightarrow (35)/(x)=(45)/(45+45)\\\\\Rightarrow x=35* (90)/(45)=35* 2=70`
