If the angles of a triangle are represented by x°, (3x + 20)°, and (6x)°, then the triangle must be

Answer 1

To find the angle measures, use algebra as shown below:

All angles of a triangle add up to 180 degrees. This is done using the following equation:

x + (3x + 20) + 6x = 180

Combine Like Terms:

10x + 20 = 180

Subtract 20 from each side:

10x = 160

x = 16

Find the angles by plugging x back:

Angle 1: 16 degrees

Angle 2: 68 degrees

Angle 3: 96 degrees

What are you asked for? These angle measures show us that the triangle is scalene, and since one angle is larger than 90 degrees, it is obtuse.
