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.
