Question 20: Please help what are sin x and cos x?

sweet [91]

Answer:

A is the correct answer.

Step-by-step explanation:

$\tan x = \frac{6}{8} = \frac{opposite \: side \: to \: \angle \: x}{adjacent \: side \: to \: \angle \: x} \\ \\ hypotenuse \\ = \sqrt{ {(opp. \: side)}^{2} + {(adj. \: side)}^{2} } \\ = \sqrt{ {6}^{2} + {8}^{2} } \\ = \sqrt{36 + 64} \\ = \sqrt{100} \\ = 10 \\ \\ \because \sin (x) = \frac{opposite \: side \: to \: \angle \: x}{hypotenuse} \\ \\ \huge{ \red{ \boxed{\therefore \: \sin (x) = \frac{6}{10}}}} \\ \\ \cos (x) = \frac{adjacent \: side \: to \: \angle \: x}{hypotenuse} \\ \\ \huge{ \purple{ \boxed{\therefore \: \cos (x) = \frac{8}{10} }}} \\$

Thus, option A is the correct answer.

Jake is comparing the prices of two laundry service companies. Company A charges $20 per load and an additional $8 as service ch

svet-max [94.6K]

X = number of loads
company A : 20x + 8
company B : 24x + 4

20x + 8 = 20(5) + 8 = 100 + 8 = 108 (company A)
24x + 4 = 24(5) + 4 = 120 + 4 = 124 (company B)
company A charges less

20x + 8 = 20(9) + 8 = 188
24x + 4 = 24(9) + 4 = 220
220 - 188 = $ 32 bucks is saved by using company A

One serving of a certain brand of yogurt contains 11 g of fat . The low - fat version contains 37.75 % less fat per serving . Ho

sasho [114]

Answer:

6.8475 grams of fat

Step-by-step explanation:

Given data

yogurt contains 11 g of fat

low - fat version contains 37.75 % less

Let us compute the value of 37.75 % of fat

=37.75/100*11

= 0.3775*11

=4.1525 gram

Hence the low - fat version contains

=11-4.1525

=6.8475 grams of fat
