Question

In a quadrilateral A B C D ,/D is equal to 150 and /A =/B=/C, find /A,/B and /C​

Answer 1

Answer:

/A=70 /B=70 /C=70 and /D=150

Step-by-step explanation:

Because in quadrilateral

sum of all angles of quadrilateral is 360

so in thi question

/A+/B+/C+/D = 360

Let be /A = x

/B = x

/C = x

given /D= 150

x + x + x + 150 = 360

3x + 150 = 360

3x = 360 - 150

3x =210

x = 210 divided by 3

x =70

therefore /A=70. /B= 70. /C= 70.

/D= 150 ( has given in question.)
