Answer to Problem 10.2EP
The value of x would be 11.
Our given triangle is an obtuse triangle.
Explanation of Solution
Given:
A triangle:
Concept used:
The interior angles of a triangle add up-to 180 degrees.
Calculation:
To find the value of x , we will equate the measure of all angles of our given triangle with 180 degrees as shown below:
Therefore, the value of x would be 11.
Let us find measure of each angle.
Since one angle of our given triangle is greater than 90 degrees, therefore, our given triangle is an obtuse triangle.
