Answer:
x=45
Step-by-step explanation:
a=135
x+135=180
x=180-135
x=45
Use the slope formula. Y2-Y1/X2-X1. Give each coordinate a label. (X1,Y1), (Y2,Y1). Then plug the numbers in and solve. 4-1/9-12. So 3/-3, which equals -1.
Answer: 5.33
Step-by-step explanation: 5 laps in 5/4 of an hour to find the final 1/3 divide 1/4 by 1/3 to find how long it will take him to run that which is 1/12 so just add to the 5/4 time he has already ran to get 16/3 or 5.33333
Answer:
1: 98
2: 82
3: 98
4: 82
Step-by-step explanation:
So 2 is 82deg then the opposite is also 82 so 4 is 82deg
Then 82+82 = 164deg, and we remain with 360deg-164deg which is = 196.
Since the other two angles will be equal (they are opposite each other) we can decide 196/2 = 98
So 3 and 1 are 98deg
