Chapter 10.1, Problem 9E
To determine

To find the value of x and classify the triangle

Expert Solution & Answer
Check Mark

Answer to Problem 9E

The value of x=15

The triangle is a scalene triangle

Explanation of Solution

Given information:

One angle of the triangle is 45

Second angle is given as 4x

Third angle is given as 5x

Calculation:

The sum of all the angles of a triangle is 180

This gives us-

  4x+5x+45=180

Add both x together

  9x+45=180

Subtract 45 from both the sides

  9x+4545=18045

This gives us −

  9x=135

Now, divide both sides by 9

  9x9=1359

This will give us-

  x=15

Since, the other two sides of the triangle is 4x and 5x

To find the value of the sides multiply it with 15

The angle of second side 4x

Multiply 4 with 15

  4x=4×15

Which gives us the value as 60

The angle of the third side is 5x

Multiply 5 with 15

  5x=5×15

Which gives us the value as 75

Conclusion- The value of x=15

One side is 45 , Second side is 60 and the third side is 75

Since, all the three sides of the triangle are different

Hence, it is scalene triangle
