Answer:
m=2
Step-by-step explanation:
Answer:
4, 6 and 8
Step-by-step explanation:
The perimeter is the sum of the lengths of the 3 sides, hence
2x + 3x + 4x = 18
9x = 18 ( divide both sides by 9 )
x = 2
The 3 sides have length
2x = 2 × 2 = 4
3x = 3 × 2 = 6
4x = 4 × 2 = 8
Sum of all the angles in a triangle = 180°
(2x + 5) + (6x - 10) + (x + 5) = 180
2x + 5 + 6x - 10 + x + 5 = 180
Combine like terms:
9x = 180
Divide by 9:
x = 20
Answer: x = 20°
