Question

In a quadrilateral ABCD,angleD is equal to 150degree and angleA=angleB=angleC.Fund angleA,angleB,angleC.​

Answer 1

Answer:

70

Step-by-step explanation:

Since angle A, B, C are equal

x+x+x+150=360. (sum of the angles of a quadrilateral is 360)

3x+150=360

3x=360-150

3x=210

X=70 degree each

Answer 2

Answer:

70 Degrees each

Step-by-step explanation:

Sum of all angles of quadrilateral = 360 degrees

And we know that Angles A= B= C are equal so let's take them as X

So, Equation Forms

X+X+X+150=360

3 X+150=360

X=(360-150)/3

X=210/3

X=70

So Angle A=70

Angle B = 70

Angle C=70
