The measure of angle 1 is 30°, and the measure of angle 2 is 110°.



What is the measure of angle 4?
40°
80°
140°
220°

Answer 1

30+110+x equal to 180
140+x equal to 180
x equals to 180-140
x equals to 40

Answer 2

Bonjour mate,



There your answer is ______,


$30 + x + 110 = 180$
$x = 180 - 140$
$x = 40$


$now \: \: \: \\ 4 = 180 - 40 \: (linear \: pair)$
$4 = 140$


So, 4 =140
