Question

Solve please. ✔️........​

Answer 1

Step-by-step explanation:

Gn:

A=109°

B=115°, Also AB||CD

To find: Angle X and Y

Const: Draw a line DE||AB||CD

Soln:

Angle DAE+ Angle DEA= 180°{Linear pair}

= 109°+ X = 180°

X=180-109

X= 71°.......(1)

Also,

Angle C° + Angle D°= 180°

Angle D°= 180-115

Angle D°= 65........(2)

From 1 and 2

X= 71+65

X=136°

Y= 180-136

Y=44°

Answer 2

Step-by-step explanation:

y= 270°

x= 90°
