Question

The angles of a triangle are in the ratio 3:4:5.The triangle is
​

Answer 1

Step-by-step explanation:

1. 3x+4x+5x = 180°
2. 12x= 180°
3. x = 180°/12
4. x = 15°

• 3x = 3×15°=45°
• 4x = 4×15°=60°
• 5x = 5×15°=75°

• Hence, this is an acute triangle

Answer 2

Answer:

180°

Step-by-step explanation:

the sum of the interior angle of a triangle will be 180°.Therefore, think of the ratio of 3:4:5 as variables followed by ''x''(3x, 4x, 5x).
