Answer:
Step-by-step explanation:
Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem, we get

⇒
⇒
⇒
⇒
Thus, the length of altitude is: 12 cm.
Now, 
⇒
⇒
Also, 
⇒
⇒
Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.
Answer:
the first one i think
Step-by-step explanation:
If you are looking for just any equivalent fraction then 34/1600 is the same as 17/800
Answer:x>7
Step-by-step explanation:
1. 6x>42
2. 6x/6>42/6
3. x>7
Lets reorder the equations
y = x - 1 (1)
y = x +1 (2)
Since both lines have the same slope (m = 1), then this is an inconsistent system with NO solution
