To find the value of x and classify the
Answer to Problem 9E
The value of
The triangle is a scalene triangle
Explanation of Solution
Given information:
One angle of the triangle is
Second angle is given as
Third angle is given as
Calculation:
The sum of all the angles of a triangle is
This gives us-
Add both x together
Subtract 45 from both the sides
This gives us −
Now, divide both sides by 9
This will give us-
Since, the other two sides of the triangle is 4x and 5x
To find the value of the sides multiply it with
The angle of second side 4x
Multiply 4 with 15
Which gives us the value as
The angle of the third side is 5x
Multiply 5 with 15
Which gives us the value as
Conclusion- The value of
One side is
Since, all the three sides of the triangle are different
Hence, it is scalene triangle
