If the angles are represented in degrees, find both angles: sin(x+7)=cos(4x+8)

garri49 [273]

Answer:

$m\angle 1 = 22\degree$

$m\angle 2 = 68\degree$

Step-by-step explanation:

$\sin(x + 7) = \cos(4x + 8) \\ \sin(x + 7) = \sin \{90 - (4x + 8) \} \\ \{ \because \cos \theta = \sin(90 \degree - \theta) \}\\ \therefore \: (x + 7) = 90 - (4x + 8) \\ x + 7 + 4x + 8 = 90 \\ 5x = 90 - 15 \\ 5x = 75 \\ x = \frac{75}{5} \\ x = 15$

(x + 7)° = (15 + 7)° = 22°

(4x + 8)° = (4*15 + 8)° = (60 + 8)° = 68°

$m\angle 1 = 22\degree$

$m\angle 2 = 68\degree$

The standard recipe for Hershey’s chocolate is 2/9 cups cocoa and 1/6 cups milk. If Hershey’s decided to pour a total of 14 cups

kifflom [539]

Answer: There are 8 cups of cocoa and 6 cups of milk to make the standard recipe for Hershey's chocolate.

Explanation:

Since we have given that

Number of cups of cocoa is given by

$\frac{2}{9}$

Number of cups of milk is given by

$\frac{1}{6}$

Since there are total number of cups of ingredients = 14

First, we find out the ratio of cups of cocoa and milk i.e.

$\frac{2}{9}:\frac{1}{6}\\\\=12:9\\\\=4:3$

So, Number of cups of cocoa is given by

$\frac{4}{7}\times 14\\\\4\times 2\\\\=8$

Number of cups of milk is given by

$\frac{3}{7}\times 14\\\\3\times 2\\\\=6$

Hence, there are 8 cups of cocoa and 6 cups of milk to make the standard recipe for Hershey's chocolate.
