Penjelasan dengan langkah-langkah:

PERSEGI = 90°

DIK : <KMN = 3x + y <KLN = 5x - 10

<KLN = 5x - 10

Y = ?

ANSWER :

<KLN = 5x - 10

90° = 5x - 10

90 + 10 = 5x

100 = 5x

[tex]x = \frac{100}{5} = 20[/tex]

<KMN = 3x + y

90 = ( 3.20 ) + y

90 = 60 + y

y = 90 - 60

y = 30

● BUKTI :

KMN = 3x + y

90 = (3.20) + 30

90 = 60 + 30

90 = 90 ( HASILNYA SAMA SAMA 90 )
