## GEOMETRY QUESTIONS-12 Question 144-) ABCD is trapezoidal, | DB | = 20 cm, if m (CBD) = 15 °; how many cm² is the area of ​​the trapezoid? Question 145-) O centered circle [BE and [BD; [AC] at point E and D; Tangent to point F, m (AOC) = 9x, m (DBE) = 6y, 2x + 3y = 23 °, how many degrees is x? SQuestion 146-) [ND]; Tangent to the circle centered B at point F, perpendicular to [NK] [BD], | NK | = | BC | = | CD | if; How many degrees is m (DBN)? Question 147-) If [AE] is tangent to the circle at point C, | AB | = | BC |, m (CBA) = 30 °, m (AEB) = 50 °, m (BCD) = α; How many degrees is α? Question 148-) If the center of the semicircle is | AE | = | ED | = | DC |, the size of the arc CB is 36 °, m (BAE) = x; How many degrees is x? Question 149-) In the circle in the figure, if m (ACB) = 25 °, m (CBA) = 75 °, m (DBE) = α; How many degrees is α? Question 150-) ABCD quadrilateral, perpendicular to [BA] [AD], perpendicular to [BC] [CD], if m (CBD) = 55 °, m (CED) = 103 °; How many degrees is m (ADB) = x?
