Question

agon
a) Triangle
3) Three angles a quadrilateral are 30°, 50°, and 120° find the fourth ang
quadrilateral​

Answer 1

Answer:

LET THE FOURTH ANGLE BE D

A+B+C+D=360

30+50+120+D=360

200+D=360

D=360-200

D=160

SO THE FOURTH ANGLE MEASURES 160 DEGREE ANSWER

Answer 2

Answer:

the other angle is 160°

let the other angle be x

Sum of all the sides of a quadrilateral is equal to 360° then,

360° = x + 30° + 50° + 120°

360° = x + 200°

360° – 200° = x

160° = x

therefore,

x = 160°
