Question

find x if the angle of a triangle is (x+40),(2x+20) and x also state which type of triangle is this

Answer 1

Step-by-step explanation:

x + 40 + 2x + 20 + x = 180° (Angle sum property)

4x = 120

x = 30°

The angles are 70, 80 , 30

It is acute angled triangle

Answer 2

Step-by-step explanation:

The angles of triangle are (x+40), (2x+20) and x

the sum of angles of triangle is 180

x+40+2x+20+x = 180

4x + 60 = 180

4x = 180-60

4x = 120

x = 30

x+40 = 70

2x+20 = 80
