Question

Quadrilateral BCDE is a kite.
What is AC ?​

Answer 1

• AC is 45 units

Explanation:

Given kite BCDE and

• CD = 53 units
• AD = 28 units
• AC = ?

We know diagonals of kite are perpendicular to each other, hence ADC is a right triangle.

Using Pythagorean, find the missing side AC:

• 
  `AC^2 +AD^2=CD^2`
• 
  `AC^2=CD^2-AD^2`
• 
  `AC=√(CD^2-AD^2)`
• 
  `AC=√(53^2-28^2) =√(2025) =45`

So AC is 45 units long
