Answer:
AB is 15
Step-by-step explanation:
To find the length of AB, use the Pythagorean Theorem. Inside the kite, the intersecting diagonals form perpendicular angles within triangles. Since these are right triangles, you can use the Pythagorean Theorem to find one of the sides of the triangle.
Use a = 8 and 17, solve for b. This will be the length of AB.
[tex]a^2 + b^2 = c^2\\8^2 + b^2 = 17^2\\64 + b^2 = 289\\b^2 = 289 - 64\\b^2 = 225\\b = 15[/tex]
