100

Step-by-step explanation:

Answer 2

Answer: 100

step/step explanation :

The angles of a triangle should sum to 180°

The angles of a triangle should sum to 180°1x + 3x + 5x = 180°

The angles of a triangle should sum to 180°1x + 3x + 5x = 180°9x = 180° Dovide both sides by 9

The angles of a triangle should sum to 180°1x + 3x + 5x = 180°9x = 180° Dovide both sides by 9x = 20°

The angles of a triangle should sum to 180°1x + 3x + 5x = 180°9x = 180° Dovide both sides by 9x = 20°The three angles are:

The angles of a triangle should sum to 180°1x + 3x + 5x = 180°9x = 180° Dovide both sides by 9x = 20°The three angles are:20°, 60°, and 100°

The angles of a triangle should sum to 180°1x + 3x + 5x = 180°9x = 180° Dovide both sides by 9x = 20°The three angles are:20°, 60°, and 100°Check: 20° + 60° + 100° = 180°
