Question

The measure of the 3 angle of quadrilateral is 30 ; 70 ; and 100 . find out the measurement of forth angle ​

Answer 1

Answer:

the fourth angle =160°

Step-by-step explanation:

let the fourth angle be x

30+70+100+x=360. (sum of all angles of quadrilateral)

200+x=360

x=360-200

x=160

Answer 2

$\huge\bold{\mathtt{\purple{A{\pink{N{\green{S{\blue{W{\red{E{\orange{R}}}}}}}}}}}}}$

30+70+100+x=360

200+x=360

X=360-200=160°
