Question 3. Work out the value of x. 105° 119° a 78° x= ​

Answer 1

Ответ:

To determine the value of x, we can use the fact that the sum of the interior angles of a quadrilateral is equal to 360 degrees. Let's calculate:

The given angles are:

105°, 119°, 78°, and x°

We know that the sum of these angles should be equal to 360°, so we can set up the following equation:

105° + 119° + 78° + x° = 360°

Combining like terms, we have:

302° + x° = 360°

To isolate x, we can subtract 302° from both sides of the equation:

x° = 360° - 302°

Simplifying further, we get:

x° = 58°

Therefore, the value of x is 58 degrees.
