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

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

Write an equation of the line that passes through (1,2) and is parallel to the line y = -5x+4

ArbitrLikvidat [17]

Answer:

y =-5x + 7

Step-by-step explanation:

y = -5x + 4

Slope = -5

Parallel lines have same slope

Slope of the parallel line to this line = -5

(1 , 2)

y -y1 =m(x - x1)

y - 2 = -5(x - 1)

y -2 = -5x + 5

y = -5x + 5 + 2

y = -5x + 7

Jaqleen can unload a grocery truck twice as fast as Marco. Together, they can unload the truck in 5 hours. How long would it tak

amm1812

Jaqleen unloads a truck in x hours and Marco takes 2x hours.

Working together (x*2x) / (x+2x) = 5 hours

2x^2 / 3x = 5 Multiplying both sides by 3x equals 2x^2 -15x = 0

x = 7.5 hours

So Jaqleen takes 7.5 hours and Marco takes 15 hours

Double-Check (7.5 * 15) / (7.5 + 15) = 112.5 / 22.5 equals

5 hours Correct!!
