Question

in a quadrilateral the angle are X degrees, X + 10 degrees, X + 20 degrees.​

Answer 1

Answer:

ĦI ΜΔŦ€ Ħ€Ř€ IŞ ỮŘ ΔŇŞŴ€Ř

Step-by-step explanation:

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

➡

➡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:

a quadrilateral have 4 angles

Step-by-step explanation:

so if you consider all 4 to be X X+10 X+20 and X+30

sum of angles of a quadrilateral = 360°

X+X+10+X+20+X+30=360

3X+60=360

3X=300

X=100°
