2. Exterior angle =
Step-by-step explanation:
1.
We can see from our given diagram that (2x+4) degrees is the measure of exterior angle of triangle PQR.
Since the measure of exterior angle of a triangle equals to the sum of the opposite interior angles. So measure of our given triangle's exterior angle will be equal to sum of measure of angle P and angle Q.
We can represent this information as:
Let us subtract from both sides of our equation.
Let us subtract from both sides of our equation.
Therefore, value of x is 56 degrees.
2. Since the measure of exterior angle of our given triangle is 2x+4, let us substitute x=56 in our expression to find the measure of exterior angle.
Therefore, the measure of exterior angle of our given triangle is 116 degrees.
