Question

pls tell value of x and y​

Answer 1

Step-by-step explanation:

2x+5°+6y-15=180 (sum of two opposite angle in a circle is 180 degree)

2x+6y=190...(1)equ

.

similarly

2y-30°+3x+10°=180

2y+3x=200....(2)equ

Now

now nar multiplied by 3 in equation 1

6x+18y=540

similarly multiplied by 2 in equation (2)

4y+6x=400

subtraction of both equation

6X+ 18y=540

4y + 6x=400

-. -. -

14y=140

y=14

Now

2y-30

2*14= 28-30

similarly

6y-15

6*14

Answer 2

Step-by-step explanation:

sum of all angles of a quadrilateral=360°

so,

2x+5°+3x+10°+2y-30°+6y-15°=360°

5x+15°+8y-45 = 360°

5x+8y-30=360°

5x+8y=360°-30

5x=330-8y___________equation 1

x=(330-8y)/5__________equation 2

putting value of x into equation 1

5(330-8y)/5=(330-8y)/5

330-8y = (330-8y)/5

5(330-8y)=330-8y

1650-40y=330-8y

1650-330=40y-8y

1320=32y

1320/32=y

41.25=y

putting value of y in equation 2

x= (330-(8x41.25))/5

x =(330-330)/5

x=0/5=0
