How long a ladder is needed to reach a windowsill 50 feet above the ground if the ladder rests against the building making an angle of
with the ground? Round to the nearest foot.
We can define trigonometric functions as ratios of the side lengths of a right triangle. See
[link] .
The same side lengths can be used to evaluate the trigonometric functions of either acute angle in a right triangle. See
[link] .
We can evaluate the trigonometric functions of special angles, knowing the side lengths of the triangles in which they occur. See
[link] .
Any two complementary angles could be the two acute angles of a right triangle.
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa. See
[link] .
We can use trigonometric functions of an angle to find unknown side lengths.
Select the trigonometric function representing the ratio of the unknown side to the known side. See
[link] .
Right-triangle trigonometry facilitates the measurement of inaccessible heights and distances.
The unknown height or distance can be found by creating a right triangle in which the unknown height or distance is one of the sides, and another side and angle are known. See
[link] .

For the given right triangle, label the adjacent side, opposite side, and hypotenuse for the indicated angle.
what's the difference between a firm and an industry
Abdul
firm is the unit which transform inputs to output where as industry contain combination of firms with similar production 😅😅

Suppose the demand function that a firm faces shifted from
Qd 120 3P
to
Qd 90 3P
and the supply function has shifted from
QS
20 2P
to
QS
10 2P .
a) Find the effect of this change on price and quantity.
b) Which of the changes in demand and supply is higher?
Demand curve shows that how supply and others conditions affect on demand of a particular thing and what percent demand increase whith increase of supply of goods
