Question

Abcd is a quardilateral incwhich ab=4.5 cm bc=3.2 cm angle a=60 angleb=105 and anle d=90​

Answer 1

Step-by-step explanation:

ab=4.5cm(length)

bc=3.2(breadth)

area of quardilateral=length*breadth

=4.5*3.2

=14.4cm

angle a=60

angle b=105

angle c=?

angle d=90

we sum of all angle of a triangle is 360 degree

a+b+c+d=360

60+105+c+90=360

255+c=360

c=360-255

c=105

angle c=105
