Answer:

80°

Step-by-step explanation:

The sum of the angles of a triangle is always 180°.

∴ 2x + 3x + 5x = 180°

                  10x = 180°

                     x = 180 / 10

                     x = 18

The biggest angle = 5x

                              = 5 * 18

                              = 90°
