Question

scalene triangle 3x-5,3x-1 and 5x+5 , what is the value of x

Answer 1

Step-by-step explanation:

USING ANGLE SUM PROPERTY :

3x+(2x+20)+(5x-40)=180

3x+2x+20+5x-40=180

10x-20=180

10x=180+20

10x=200

x=20

All the angles are :

3x=3×20=60

2x+20=2×20+20=40+20=60

5x-40=5×20-40=100-40=60

All the angles are of 60° therefore it is an equilateral triangle.
