I'd say that, if the angles S and U are equal, as the SV and UV segments move towards each other, they meet at vertex V, the angles they make, angle SVT and UVT, have to be equal, because the side TV is shared by both, and has the same direction.
now, side TV is on both triangles, and is shared by both, so is the same length, so TV on one triangle is equal to TV on the other
check the picture below
so, you have one Angle, another Angle, and then a Side

Answer:
y = 3x - 5
Step-by-step explanation:
We know that the equation 'y = 3x + ?' intersects the point (1, -2). This means that when x = 1, y = -2 in out equation above. To solve this just plug in the x and y values to get '?'.

Now that we know '?' is -5, we write it back into slope intercept form, so our final answer is y = 3x - 5
Answer:
$159.95
Step-by-step explanation:
Let price of trumphet be defined by 
price of clarinet = $139.95
Number of clarinets sold = 19
Earning through clarinets' sale = 
Total earning of store = $4578.45
Earning through trumphets' sale = 
price of one trumohet = 
price of clarinet = $159.95
