Question

in a quadrilateral abcd ad = 13 cm dc = 12 cm bc‌ = 3 cm and angle abd = angle bcd = 90 digree calculate the length of ab

Answer 1

USING PYTHAGORAS THEOREM,

BD² = BC² + CD²

BD² = 3² + 12²

BD² = 9 + 144 = 153

BD = √153

NOW,

AB² = AD² - BD²

AB² = 13² - (√153)²

AB² = 169 - 153

AB² = 16

AB = 4 CM.

HENCE,

SIDE AB = 4 CM.
