Question

Q.8. One Angle of a quadrilateral is of 108° and the remaining three angles are equal.

Find each of the three equal angles

a)84°,90°,90° b) 84°,84°,84° c) 90°,90°,84° d) 90°,84°,90°​

Answer 1

Answer:

Answer is option B. ALSO MARK ME AS BRAINLIEST IT WILL HELP ME TO RANK UP!!!!

Step-by-step explanation:

Let the remaining three equal angles be x.

We know, Sum of all interior angles of a quadrilateral is = 360

108 + x + x + x = 360

108 + 3x = 360

3x = 360 – 108

3x = 252 x = 252/3

x = 84

Each of three equal angles, x = 84.

Answer 2

Step-by-step explanation:

Given

One angle of quadrilateral =108

WKT

sum of four angles is = 360

Let the other angle be x

x+x+x+108=360

3x=360-108

3x=252

x=252/3

x=84

There fore the angle is 84
