Question

In a quadrilateral, the angles are x°,( X+10) °(X+20)° and ( X+30 )° , then the measure of greatest angle is

Answer 1

Answer:

The biggest angle is 136

Step-by-step explanation:

By angle sum property of quadrilateral

X + X - 10 + X + 30 + 2 x= 360

5 x + 20=360

5x=340

x=68

now the angles are 68, 58, 98, 136

the biggest angle is 136 that is 2x

Answer 2

x+x+10°+x+20+x+30°=360°

4x+60°=360°

4x=360°-60°

4x=300°

x=300/4

x=75°

greatest angle=x+30°=75°+30°

=105°
