Express sin A,cos A and tan A as ratios

OverLord2011 [107]

Answer:

Part A) $sin(A)=\frac{2\sqrt{42}}{23}$

Part B) $cos(A)=\frac{19}{23}$

Part C) $tan(A)=\frac{2\sqrt{42}}{19}$

Step-by-step explanation:

Part A) we know that

In the right triangle ABC of the figure the sine of angle A is equal to divide the opposite side angle A by the hypotenuse

$sin(A)=\frac{BC}{AB}$

substitute the values

$sin(A)=\frac{2\sqrt{42}}{23}$

Part B) we know that

In the right triangle ABC of the figure the cosine of angle A is equal to divide the adjacent side angle A by the hypotenuse

$cos(A)=\frac{AC}{AB}$

substitute the values

$cos(A)=\frac{19}{23}$

Part C) we know that

In the right triangle ABC of the figure the tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A

$tan(A)=\frac{BC}{AC}$

substitute the values

$tan(A)=\frac{2\sqrt{42}}{19}$

Sarah bought a sweater at the sale price of $18 the original cost of the sweater was $40 what percent represents the discount th

igomit [66]

Let’s remember the most basic thing in percentages, the equation.

Percent x Whole = Part.

We know the whole, and the part, but we are trying to find the percent, so we have to divide the two, first turn your whole and part into a decimal.

Percent x 0.4 = 0.18, so we divide 0.18 by 0.4

0.18/0.4 = 0.45

0.45 = 45%

3. a) p∝1/m
P=k/m
48=k/9
48×9=k
k=432

the equation is: p=432/m

b) p∝1/m
P=k/m
P=432/12
P=36
