Question

What is the answer and please explain it

Answer 1

Answer: See steps below for answer

Explanation:

1) Set up an equation

• 40 + x + 3x = 180
• 4x + 40 = 180
• 4x = 140
• x = 35

_____

Part 2:

One angle: 40 degrees

Second angle: x or 35 degrees

Third angle: 3x or 105 degrees

Therefore answer is

35, 40, 105

Answer 2

x=35°

Explanation:

40° + 3x° + x°= 180°

40° + 4x° =180°

4x° = 180° - 40°

4x° = 140°

x° = 35°

From least to greatest :

x=35°

3x=35×3

=105°

therefore in order : 35°, 40°, 105°
