Question

three angles of a scalene triangle are in the ratio 3:4:5. fund the measures of its angles​

Answer 1

Answer:

Let the angles be 3x , 4x , 5x , then

3x + 4x + 5x = 180⁰

12x = 180⁰

x = 180/12

x = 15⁰

Angles are 3x = 3×15 = 45⁰

4x = 4×15 = 60⁰

5x = 5×15 = 75⁰

Answer 2

Step-by-step explanation:

3x+5x+4x =180 ( Angle Sum Property of triangle)

12x=180

x=180/12

x=15

Angles of scalene triangle

3x=3×15=45

4x=4×15=60

5x=5×15=75
