Question

I will surely mark as brainliest if u give me the correct answer of these questions. (1)If angles A,B,C,D of the quadrilateral ABCD takenbin order are in the ratio3:7:6:4. ABCD is a........... (2)ABCD is a rhombus such that angle ACB=40° than angle ADB is

Answer 1

Let the angles be x
So,
3x + 7x + 6x + 4x =360*
20x=360*
x=12*

Now, angle A= 3 *12= 36
B=7*12=84
C=6*12= 72, D= 4*12= 48
2)
Angle ACB will also equal to 40*
