Question

the sum of of the two angles of a quadrilateral is 145 degree and other two angles are in the ratio is 2 ratio 3 find angles​

Answer 1

Answer:

Sum of two angles of a quadrilateral is given- 145°

and the ratio of the other two angles is given to be 2/3 or 2:3

now let the angles be 2x and 3x

we know that sum of all angles of quadrilateral is 360°

therefore, 2x°+3x°+145°=360°

5x=360-145

5x=215

x=215/5

x=43°

now the other two angles are--》》

2x = 2*43=86°

and

3x=3*43=129°

hope this would help you,if it did then do follow me :)))☺️
