Answer:

Step-by-step explanation:
Given:
The triangle is shown below.
We know that the sum of all interior angles of a triangle is equal to 180°.
Therefore,

Now, plugging the value of 'x' in each angle measure and determining its values. We get:

Therefore, the value of 'x' is 36° and the measure of the three angles are 36°, 71° and 73°.
The way your problem is set it should be simplified to this....4x + 55
The answer to question 1 is n=-17, and the answer to question 2 is y=-5.8 (<u>could also be seen as -29/8</u>)
