Question

If angle A is double of angle C and angle b & angle D are 70 & 120. Find angle A and angle C

Answer 1

this is the same method for this question

Answer 2

Answer:

Step-by-step explanation:

let the angle b,c,d be x,x,x                         [as the three angles are equal]

now angle sum property of quadrilateral= 360 degree

given;angle A=150 degree

therefore,

angle A+angleB+angle C+angle D=360 degree

150+3x=360 degree

3x=210

x=70

hence,angles are 150,70,70 and 70 degrees
