Question

The sum of the two angles of a quadrilateral is 145degree.the other two angles are in the ratio 2:3 find the angles

Answer 1

Let the ratio of angles be 2x and 3x.

As we know, sum of angles of quadrilateral is 360 degrees.

2x + 3x + 145 = 360

5x = 360 - 145

5x = 215

x = 43

2x = 86

3x = 129

Answer 2

Here is your answer below,

we know that the total sum of angle of quadrilateral is 360°

let the angel be x

Given values are ratio of two angle is 2:3 it means 2x & 3x and sum of two angle is 145°

Now solution is,

2x+3x+145 = 360

5x = 360 -145

5x = 215

x = 215/5

x = 43

so that the angle is

2x = 2×43 =86°

3x = 3×43 = 129°
