Question

please tell answer of this question​

Answer 1

Answer:

180-105 (to find the first unknown interior angle)

= 75

Now angle z will also be equal to 75 (alternate angles)(lines are parallel-given)\

So angle z=75

Now we know

40+y+z= 180

40+y+75=180

115+y=180

y= 180-115

y=65

Now sum of all interior angles of triangle is= 180

So, we know that

interior angle 1 + y+ x= 180

interior angle one= 75

y= 65

So 75+65=

140

Therefore x= 180-140=40

x=40 (confirmed as it is also alternate to angle 40)

y=65

z=75
