I simplified it to, 2x^2 - 12+13
Since triangle STU and TVW are similar angle VWT and SUW are equal, this means:
106-5x=7x-14
(106)+(14)=(7x)+(5x)
120=(12x)
10=(x)
Angle VWT=106-5x=106-(5)(10)=56
Answer:
a=-2
Step-by-step explanation:
If a line segment has one endpoint on the line y=x, then its coordinates are (b,b). The first endpoint of the segment is at point (a,0). We can find the coordinates of the midpoint of this segment as the average value:
Thus,
From the second equation
Substitute it into the first equation:
