Answer: 7cm
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the length of the 3 sides together. Let the third side be x , then
x + 9 + 6 = 22
x + 15 = 22
Subtract 15 from both sides , that is
x = 22 - 15
x = 7
Therefore : the third side is 7cm
Cross Multiply. 25 * 24 and 40 * 15
Yes, they are proportional
Answer:
d = 7.2
Step-by-step explanation:
We can cross multiply the equation to get:
6 * 30 = 25 * d
(* is multiplication sign by the way)
180 = 25d
Divide both sides by 25 to get:
d = 7.2
