All angles in a quadrilateral add to 360
x is supplementary to that other angle, call it y
the angles inside are 40, 80, 110 and y
40+80+110+y=360
230+y=360
minus 230 both sides
y=130
that is supplementary to x (adds to 180)
x+y=180
x+130=180
minus 130 both sides
x=50
x=50 degrees
i believe it is 645, 500 !
Answer:
hold on...
Step-by-step explanation:
Answer:
1. angle AEB and angle DEF
2.angle AEB and angle CEB
3. angle AEF and angle DEF
4. 120 degrees - vertical angles have the same degree
5. 13 degrees - vertical angle
6. 180-110 = 70 degrees - supplementary
7. 180-65 = 115 degrees - supplementary
Step-by-step explanation:
vertical angle = angles that are opposite of each other where two lines cross
complementary angle = angles that make up the sum of 90 degrees
supplementary angle = 2 angles with the sum of 180 degrees
