Given:
Eighteen 2.5 gallon buckets are needed to fill a cistern with water.
To find:
The constant of variation.
Solution:
If y is directly proportional to x, then
Where, k is constant of variation.
In the given problem, water in cistern (w) is directly proportional to number of buckets (n).
(Capacity of each bucket is 2.5 gallons)
Therefore, the constant of variation is 2.5.
Answer:
The other two sides of given isosceles triangle are 6.53 inches long.
Step-by-step explanation:
in the figure below,
ABC is an isosceles triangle has angle measure 40, 40, and 100. The side across from the 100 angle is 10 inches long an let this side be b
Let the other two be a inches long .
We have to find the measure of side AB.
Sine rule is an equation relating the lengths of the sides of a triangle to the sines of its angles. According to the law,
For a triangle Let B stands for the angle at B. Let C stand for the
angle at C and A for angle A. Also, let b = AC, a = BC and c = CB = a.
............(1)
Using sine rule,
Putting values in (1),
Considering first two ratios,
(approx)
Since, the triangle is isosceles so, other two sides are equal.
Thus, other sides are 6.53 inches long.
