Question

if x=27 find y no spamming​

Answer 1

Answer:

y=4.2

Step-by-step explanation:

(5y+20)°

y=20/5

y=4.2

Answer 2

Answer:

21

Step-by-step explanation:

Given,

x = 27

∠CAD = ( 5y + 21 )°   { From diagram }

∠DAB = 2x  { From diagram }

To find : y = ?

∠CAD + ∠DAB = 180° { Linear pair }

( 5y + 21 )° + 2x = 180°

( 5y + 21 )° + 2 ( 27 ) = 180°

( 5y + 21 )° + 54 = 180°

( 5y + 21 )°= 180 - 54

5y + 21 = 126

5y = 126 - 21

5y = 105

y = 105 / 5

y = 21
