Answer:
x=20
Step-by-step explanation:
form a ratio
28:7
4:1
x:5
x=20
Answer:
Quadratic polynomial is x^2 - x - 20
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 .
