Sum of angles of a linear pair = 180. So angle with measurement 142 and the adjacent angle to it have a sum = 180.
THerefore 142+y=180
Subtracting 142 from both sides
y = 38
Now in the down right sides corner triangle
38+49+w=180
87+w=180
Subtracting 80 from both sides,
w = 93
So the measurement of angle w = 93 .
There are two sides in a coin so the chance of getting tails is 1/2, which would be 0.5.
I'm not sure tho.
Answer:
Step-by-step explanation:
7.
y= -2x+2
8.
y= -x-3
9.
y= 2/3 x + 1
10.
I'd put a point on (0, 15) , (1, 30), (2, 45) and etc....
Use a ruler to connect these points and use it to draw a straight line that hits all these points.
Good luck
