Question

how do i find r? (see figure)

Answer 1

Triangle ABC and ADE are congruent

Answer 2

That means\[
7+p = c(5+9)
\]

Answer 3

Ac = 14
Ok ?

Answer 4

\[
(r+7)^2 = p^2 + (5+9)^2
\]

Answer 5

@wio :Dont give answer :(
I have a better way :(

Answer 6

Give me a medal please.

Answer 7

@stupidinmath :Never do this work:(

Answer 8

@E.ali ur method looks simple... good observation :)

Answer 9

@ganeshie8 :Thank u friend :)

Answer 10

AC = 14
since AE = AC, p = 7
p^2+5^2 = DE^2, you have DE

since DE = BC, you have r

Nice :)

Answer 11

@ganeshie8 :thank u friend :)
Realy right :)
@stupidinmath :I have more ways too :)

Answer 12

:) *typo, (p+7)^2+5^2 = DE^2

Answer 13

@ganeshie8 , said the simplest solution :);)

Answer 14

thats actually @E.ali method.. :) wud love to see other ways aswell =)

Answer 15

thank you so much guys! :D
