Question

find the value of x and y the following figure​

Answer 1

Answer:

y = 30, x = 150

Step-by-step explanation:

Sum of all the angles in a triangle = 180

so, 70 + 80 + x = 180

     150 + x = 180

      x = 180 - 150

      x = 30

x and y are in a straight line.

so x + y = 180

30 + y = 180

y = 180 - 30

y = 150

<A = 70°

<B = 80°

<C = y = ?

We know,

<A + <B + <C = 180°

=> 70° + 80° + <C = 180°

=> 150° + <C = 180°

=> <C = 180° - 150°

=> <C = 30°

Now, We know that opposite angles are equal.

hence, <A = 70° = x

We got,

X = 70°

Y = 30°
