Answer 2

Answer:

60°

Step-by-step explanation:

Given that,

There is triangle formed by three sides and one side is parallel to a line as shown in figure.

We have to find the value of X.

As per given condition,

X is equal to {180° - sum of angle of two sides}.

Because ,

a sum of angles of a triangle = 180°.

And x is corresponding to not given value of the triangle.

So, x is equal to {180° - (sum of angle of two sides)}

Now,

=> {180° - (65° + 55°)}

=> {180° - 120°}

=> 60°.

Therefore, angle X = 60°.

FORMULA

• Sum of angle of triangle is 180°.

• Perimeter of triangle is (a + b + c),

where a,b, c are length of side of triangle.
