Question

FIND THE VALUE 0F THE UNKOWN 'X' AND 'Y' IN THE FOLLOWING DIAGRAM

Answer 1

Answer:

hope it will help you

Step-by-step explanation:

120-180=y

=60

so now,

Q+Y-180=X

50+60-180=X

110-180=X

X=70 (ans)

Answer 2

So, the first step would be to find "y" so you have atleast 2 interior angle values (so y ou can find the third).

If you look at y, and the 120 degrees they form a supplementary angle. I suggest you look up what that is, because the internet might provide a helpful diagram.

In supplementary angles the sum of 2 angles are equal to 180 degrees.

So, Y + 120 = 180. Solving for "y" you would get 60.

Therefore, y = 60.

Finding the value of x:

The sum of the interior triangle is 180, because (3-2) x 180 = 180.

So, set up a equation: 50 + 60 + x = 180. Solve for the "x".

Therefore, x = 70
