Answer:
i do believe the answer is 6/7
Answer:
N.14 ABC = 5x+20, N.15 ABE = 90. N.16. 123, 29, 28. N.17 K = 80
Step-by-step explanation:
Because of vertical angles, 5x+20 = 3x+66.
5x=3x+46
2x = 46
x = 23
Sum of angles in a circle is 360
360-135-135=180
ABE = CBD because vertical angles.
180 / 2 = 90
16.
Sum of angles in triangle is 180
180=123-x-2-x-3
x = 31
123, 29, 28.
17.
Sum of angles in triangle is 180
180-72-28 = 80
K = 80
Answer:
The final angle is 50
Step-by-step explanation:
All quadrilaterals have interior angles that add up to 360. So we can subtract these numbers from 360 to get the final angle.
360 - 90 - 100 - 120 = 50
1.03428571 is the answer.
