Answer:
We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.
Step-by-step explanation:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.

rate of the current: 18 km/h
Step-by-step explanation:
Answer: The rate of change is 250%
Step-by-step explanation: The weight is multiplied by 2.5 or 250%
Answer:
3/2
Step-by-step explanation:
1) Convert into the slope intercept formula.
4x + 6y = 8
6y = -4x + 8
y = -4/6 + 4/3
y = -2/3 + 4/3
2) Find the opposite reciprocal of the slope.
The opposite reciprocal of -2/3 is 3/2.
The perpendicular slope of the line 4x + 6y = 8 is 3/2.
Answer:
Therefore to get 4 feet per second the values of distance and time are
Step-by-step explanation:
Speed:
Speed is defined as the rate of distance covered in per unit time.
It is given as
It's unit is meter per second
So to get 4 feet per second
i.e Distance = 4 feet
Time = 1 second
Also we can have other values too like
Distance = 8 feet
Time = 2 second
and so on
Therefore to get 4 feet per second the values of distance and time are
