Hint: Given the angles of a triangle are , , and degrees. As we know, the sum of the measure of all the three angles in a triangle is degrees. So, in this question, we will sum up all the three measures of the angle of the triangle and equate it to degrees i.e., and then we will simplify it to find the value of .
Complete step by step answer:
Given the angles of a triangle are , and degrees, we have to find the value of .
As we know, the sum of the measure of all the three angles in a triangle is degrees.
On adding all the three measures of the angle of the triangle and equating it to degrees, we get
On simplification, we get
On dividing both the sides of the equation by , we get
On calculating, we get
Therefore, the value of is .
Note:
Here, the question is of a triangle. Like the sum of the measures of the angles of a triangle having three sides is always . Similarly, the sum of the measure of the angles of a quadrilateral having four sides is always , the sum of the measure of the angles of a pentagon having five sides is always and the sum of the measure of the angles of a hexagon having six sides is always .
