Question

c)find the value of x and y in each of the following figures.
​

Answer 1

$\huge\mathfrak\blue{Answer:-}$.

>>Y = 180 -(50+70)

Y = 180-120°

Y= 60°

Now for finding X draw a line from 90° to y

And 90° will become 45°

Now 90+45+x=180°

or x = 180- 135

or x= 55°

Thus if both angles are same ,

Then X = 55° {Ans}

Answer 2

Answer:

the sum of 50° + y + 70° = 180

so 120 + y = 180

y= 180-120

sum of all the angle are =180

so , 40+ 60+ X + x= 180

100 +2x = 180

x= 80/20 x=40
