Answer 1

Answer:

hope it helps you!!!!!!

Answer 2

Answer:

x=12 ,y=15

Step-by-step explanation:

In ∆ADB,

∆ADB=90°

$ab {}^{2} = {ad}^{2} + {bd }^{2} \: \: {pythagoras \: theorem }\\ {13}^{2} = {x}^{2} + {5}^{2} \\ 169 = {x}^{2} + 25 \\ {x}^{2} = 169 - 25 \\ {x}^{2} = 144 \\ x = 12$

In ∆ADC

∆ADC=90°

$ac {}^{2} = {ad}^{2} + {dc}^{2} { pythagoras \: theorem} \\ {y}^{2} = {12}^{2} + {9}^{2} \\ {y}^{2} = 144 + 81 \\ {y}^{2} = 225 \\ y = 15$
