Question

please answer it..................... ​

Answer 1

Answer:

A+B=180

3y+[2y-5]=180

5y-5=180

5y=185

y=37

D=C[opp. angle]

D+C=180

[2y-5]+3x+3=180

[2(37)-5]+3x+3=180

74-5+3+3x=180

3x+72=180

3x=180-72

3x=108

x=108/3

x=36

therefore option c is correct

Step-by-step explanation:

Answer 2

Step-by-step explanation:

3y°+(2y-5)° =180° (by corresponding angles)

=>3y +2y -5= 180°

=>5y =180° +5

=>y =185/5

=>y=37°

Again ,

(2y-5)°+ (3x+3) =180° (by corresponding angles)

=>(2×37-5) +(3x+3)=180°

=>74-5 +3x +3 =180°

=> 3x + 72 =180°

=> 3x =180°-72

=> x=108°/3

=>x=36°

I hope it'll help you
