Question

three angles of a quadrillateral are in the ratio 2:3:5 and the fourth angle is 90 degree find the measure of three angle​

Answer 1

Answer:

let 2:3:5 be

2x:3x:5x

sum of interior angles of quadrilateral is 360°

so, 2x+3x+5x+90°=360°

10x+90°=360°

10x=360°-90°=270°

10x=270°

x=270/10

x= 27

2(27)=54°

3(27)=81°

5(27)=135°

Answer 2

Answer:

The angles are 54°, 81°, 135°

Step-by-step explanation:

let the angles be 2x, 3x, and 5x

According to question

2x + 3x + 5x + 90 = 360 (As sum of all angles of a quadrilateral is 360°)

=> 10x + 90 = 360

=> 10x = 360-90

=> 10x = 270

=> x = 27

The angles are 27*2 = 54°, 27*3 = 81° and 27*5 = 135°
