1.In a right triangle, <A and <B are acute. Find the value of csc A, when tan A = 8/15.

bekas [8.4K]

Answer:

(1) $csc A=\dfrac{17}{8}$

(2) $sec A=\dfrac{17}{15}$

Step-by-step explanation:

<u /> $Tan A=\dfrac{8}{15}\\$In Trigonometry, $Tan A=\dfrac{Opposite}{Adjacent}\\$Therefore:\\Opposite=8, Adjacent=15$ <u />

Using Pythagoras theorem

$Hypotenuse^2=Opposite^2+Adjacent^2\\Hypotenuse^2=8^2+15^2\\Hypotenuse^2=289\\Hypotenuse^2=17^2\\Hypotenuse=17$

<u>Question 1</u>

Now, cosecant = 1/sin

Therefore:

$csc A=\dfrac{Hypotenuse}{Opposite}\\csc A=\dfrac{17}{8}$

<u>Question 2</u>

Now, secant = 1/cos

Therefore:

$sec A=\dfrac{Hypotenuse}{Adjacent}\\sec A=\dfrac{17}{15}$

A cup of dog food weighs 1 and 7/8 ounces. My dog eats 5 cups per day. How many ounces of dog food does he eat?

Aneli [31]

Answer:

9 3/8 ounces of dog food

Step-by-step explanation:

1 cup = 1 7/8 ounces

1 7/8 + 1 7/8 = 2 14/8 = 3 6/8

3 6/8 + 1 7/8 = 4 13/8 = 5 5/8

5 5/8 + 1 7/8 = 6 12/8 = 7 4/8

7 4/8 + 1 7/8 = 8 11/8 = 9 3/8
