Step-by-step explanation:
The perimeter of a triangle is calculated by adding all three side lengths together
That means x + 3 + x + 4 + x + 1 = 17 add the like terms
3x + 8 = 17
3x = 9
x = 3
BC = x + 3 ➡ 6
CD = x + 4 ➡ 7
BD = x + 1 ➡ 4
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle.
Sum the 3 sides and equate to 17, that is
x + 3 + x + 1 + x + 4 = 17, that is
3x + 8 = 17 ( subtract 8 from both sides )
3x = 9 ( divide both sides by 3 )
x = 3
Thus
BC = x + 3 = 3 + 3 = 6
CD = x + 4 = 3 + 4 = 7
BD = x + 1 = 3 + 1 = 4
