Question

Find the value of x and y.​

Answer 1

Answer:

Angle ACB + ACD= 180° [ Linear pair ]

=> y + 128°= 180°

=> y = 180° - 128°

=>y = 52°

x + y + y = 180° [ Sum of all angles of a triangle ]

=> x + 52° + 52° = 180°

=> x + 104° = 180°

=> x = 180° - 104°

=> x= 76°

Step-by-step explanation:

Hence x = 76° ,y = 52°

Answer 2

Answer:

X=76° and y=52°

Step-by-step explanation:

1. we know that,angle bcd=180°
2. therefore,y=180-128=52°
3. in a triangle,sum of angles=180°
4. 52+52+x=180
5. 104+x=180
6. x=76°
