Question

find the value of X
wrong answer will be reported​

Answer 1

Answer:

7y+5y =180 straight angles.

y = 180/12 = 15

3y+5y+x = 180 sum of all angles of triangle

then X = 180-8y = 180-120= 60° Answrr...

Answer 2

Answer:

Since,7y and 5y are in a straight line

So,7y+5y=180

====>12y =180

===> y =180/12

===> y = 15

3y = 3×15

3y = 45

5y = 5×15

5y = 75

We know that ,

Sum of all angles of a triangle =180

So,

3y+5y+x =180

45+75+x =180

120+x=180

x=180-120

x = 60
