The correct answer would be 1in, if you want to check and see if im right use a 12 inch ruler and check
hope this helps out.
50 degrees is one while the other two are 130 degrees
I think that it's 3.8 because the triangles are congruent but I might be wrong.
Speed = Distance / Time
Distance = Speed*Time
For this problem, we should bear in mind that current speed has an impact on the boat speed...
for upstream, the boat goes against the current, and so its speed is
U = V - C
where V is the speed of the boat
C is the current speed
for downstream, it will be:
D = V + C
Convert the problem into mathematical equations:
4D + 3U = 116
3D + 4U = 108
4(V+C) + 3(V-C) = 116
4V + 4C + 3V -3C =116
7V + C = 116
3(V+C) + 4(V-C) = 108
3V + 3C + 4V - 4C = 108
7V - C = 108
Solving the equations:
7V + C = 116
7V - C = 108
14V = 224
V = 16km/hr —-> speed of boat
to get C:
7(16) + C = 116
C = 4km/hr
Answer:
H=15
Step-by-step explanation:
Do the problem backwards 17-2=?
17-2=15 so 15+2=17 so h=15
