Question

one angle of a quadrilateral is 180 degree the other three angles are in ratio 3 is to 4 is to 5 find the angles​

Answer 1

Answer:

Step-by-step explanation:

Let the unknown angles in the ratio 3:4:5 be 3x,4x,5x

As the sum of angles of a quadrilateral =360,

180+3x+4x+5x=360

Thus we will get x=15 degree

So the unknown angles are:

3x=3*15=45 degree

4x=4*15=60 degree

5x=5*15=75 degree
