Question

Please Help Me How to do this..

Answer 1

It is

They each have a right angle and they share an angle (the one in the right corner)

This means that they share 2 angles and therefore share all angles

edit: pt2


`(x)/(10+4) =(3)/(4)`


`(x)/(14)(times2) = (3)/(4)(times7)`


`(2x)/(28) = (21)/(28)`

2x = 21
x=10.5




`(y)/(14)(times2)= (5)/(4)(times7)`


`(2y)/(28) = (35)/(28)`

2y=35
y=17.5
