The value of c in the missing triangle is 39
<h3>Right angle triangle:</h3>
- A right angle triangle is a triangle that has one of its angle as 90 degrees.
The side c can be found using Pythagoras theorem.
Therefore,
c² = a² + b²
c² = 36² + 15²
c² = 1296 + 225
c = √1521
c = 39

Answer:
-7
Step-by-step explanation:
-1 x -1 = 1
4 x -2 = -8
1 + (-8) = -7
Answer:
9.45 per dozen
Step-by-step explanation:
3.15/4 = x/12
Cross Multiply
4x = 37.8
Divide both sides by 4
x=9.45
9.45 per dozen
Answer:
- boat: 6 mph
- current: 2 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
speed = distance/time
For boat speed b and current speed c, the speed downstream is ...
b +c = (16 mi)/(2 h) = 8 mi/h
The speed upstream is ...
b -c = (16 mi)/(4 h) = 4 mi/h
Adding the two equations eliminates the c term:
2b = 12 mi/h
b = 6 mi/h . . . . . divide by 2
Solving the second equation for c, we get ...
c = b -4 mi/h = 6 mi/h -4 mi/h = 2 mi/h
The speed of the boat in still water is 6 mi/h; the current is 2 mi/h.
