I could not see the first question so i couldn't answer.
2) Draw a horizontal line and cut it in half with a vertical angle. 4 equal quarters will form. There each quarter is 90° (right angle is exactly 90°angle)
3) Just add the two angles.
x =13+19
x= 32° (Answer)
4) We must know the other angle value in order to find x. So considering both the angles are equal,
2x = 44
x= 22° (Answer)
5) Yes, x = 80° because the line cutted is a straight line and the value of a straight line is 180°
6) Supplementary angles total 180°
Complementary angles total 90°
7)Opposite angles is equal when two straight lines intersect. So,
14x - 16 = 12x + 22
14x-12x=22+16
2x= 38
x= 19° (Answer)
8) Corresponding angles
9) 140°
Answer:
8/25
Step-by-step explanation:
8/25 • 2/1 = 16/25. To work this backward, you need to know that any whole number can be converted into a fraction by putting the number over one. 2 = 2/1. divide 16 by 2 and you get 8, and that 8 goes over 25. Then, set up your equation. 2/1 • 8/25 = 16/25.
Answer:
Since 
= 6 and 
= 7 it is known that 
is between 6 and 7.
Step-by-step explanation:
The answer should be x=100
