i will mark it as brainliest​

Answer 1

Step-by-step explanation:

/A+/C =180°

or,2x+4+4y-4=180°

or,2x+4y=180°

or,x+2y=90°

/B+/D =180°

or,x+10+5y+5=180°

or,x+5y=180°-15

from (1),(2)

x+5y=180°-15

x+2y=90°

(-). (-). (-).

3y=90°-15

or,y=3(30°-5)/3

=30°-5

x=180°-15-5y

=180°-15-150°+25[ y=30°-5]

=30°-10
