Question

In a quadrilateral , the angles are x degrees , x+ 10 degrees , x + 20 degrees, x + 30 degrees . find the angles

Answer 1

$\boxed{\colorbox{red}{HEY MATE!!}}$

as we know that Sum of angles In a quadrilateral = 360°

➡$\colorbox{teal}{Given Angles:--}$

➡the angles are x° + x+ 10° + x + 20 °s + x + 30°

➡x° , x+ 10° , x + 20 °s, x + 30 = 360°

➡ 4x = 360°

➡x = 75°

↪Measure of angle = x = 75°
↪Measure of angle =x + 10°=85°
↪Measure of angle =x + 20°=95°
↪Measure of angle =x + 30°=105°

Answer 2

ANSWER is here

Angles are x° ,(x+10)°,(x+20)°,(x+30)°.

By angle sum property of quadrilateral

x+(x+10)+(x+20)+(x+30)=360

x+x°+10°+x+20°+x+30 = 4x+60=360

4x+60°=360°

4x=360°-60°=300°

X=360/4

=75°

So x = 75°
