ΔABC is a right triangle
By the Pythagorean theorem:
AC = √(BC² - AB²) =√(5²-3²) = √(25-9) = √16 = 4
ΔBED is a right triangle
DE = 4
BE = AB + AE = 3 + 4 = 7
By the Pythagorean theorem:
BD = √(BE² + DE²) =√(7²+4²) = √(49+16) = √65
Answer: BD = √65
X = 180 - 90 - 12 = 78° (Sum of all angles in a triangle is 180)
