Question

Abcd is a trapezium with ab parallel to dc angle a =45 angle b =45 c? D?

Answer 1

the total measurement of trapezium=180°

angle a= 45°

angle b=45°

find the value of c,d

the opposite side of trapezium is 180°

angle a+angle c=180°

45°+angle c=180°

angle c=180°-45°=135

angle b+angle d=180°

45°+angle d=180°

angle d=180°-45°=135°
