What is the value of x?

The value of x is

Step-by-step explanation:

Here we have given two angles of triangle are 80⁰,55⁰.

We need to find the third angle of triangle (x).

Now, According to the question.

Hence, the value of x is 45⁰.

To verify, we'll add all angles of triangle and check the sum of triangle is 180⁰ or not.

Hence Verified!

eve and marks ratios are equivalent

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
