Question

X-30, x-45, x+15 are the 3 sides of a triangle then x

Answer 1

Answer:

X+X+x= 180

30+45+15=90-180

Answer 2

Answer:

x-30+x-45+x+15 =180

(Angle sum property)

x+x+x-30-45+15=180

3x-60=180

3x=180+60

3x=240

x=240÷3

x=80

therefore the sides of triangle are:

x-30=80-30=50

x-45=80-45=35

x+15=80+15=95

hence the sides of triangle are 50,35,95

hope it helps u mate
