Question

in a quadialteral the angles are x °,(x+10)°,(x+20)°,(x+30)° find the angles

Answer 1

hi friend

here is your answer

angle sum property of a quadrilateral = 360
x + x + 10 + x + 20 + x +30 = 360
4x + 60 = 360
4x = 360 - 60
 x = 300/4
x=75

therefore  the angles are 75, 85, 95, 105

hope it helps

Answer 2

x°+(x+10)°+(x+20)°+(x+30)°=180°. ......sum of all measures of a quadrilateral is 180°
4x+60 =180
4x=180-60
4x=120
x=120/4
x=30°



x=30°
x+10=30+10=40°
x+20=30+20=50°
x+30=30+30=60°
verify your answer :)
