Answer 1

15 cm

Answer 2

sorry 30 cm

Answer 3

can u explain dear shabeer?

Answer 4

do you know Pythagoras theorem?

Answer 5

Answer 6

Yeah absolutely right. This question you try to solve, though I will help you.

Answer 7

Which line segment can you calculate with the Pythagoras theorem?

Answer 8

20^2 + b^2 = 25^2

Answer 9

Right

Answer 10

And b=?

Answer 11

400 + b^2 = 625
-400 -400
b^2 = 225
b=....15?

Answer 12

Absolutely right, so what does the small line on line segment AB, BC and BE indicate

Answer 13

that its congruent?

Answer 14

Yeah then calculate Line segment AC

Answer 15

so just add 15 and 15? So 30?

Answer 16

Yes, you knew the answer. Just try it atleast once or twice, using the basic concepts you know. That would solve the problem.
