Question

Find LR, given kite FLRD with diagonals intersecting at A and FA = 4, AR = 12, LA = 5

Answer 1

LR = 13

Explanation:

LAR is a right triangle and if two sides are known you can you use the pythagorean theorem to find the missing side

LA = 5

AR = 12

5² + 12² = LR²

LR² = 25 + 144

LR² = 169

LR = √169 = 13
