The sine of any acute angle is equal to the cosine of its complement. The cosine of any acute angle is equal to the sine of its complement. of any acute angle equals its cofunction of the angle's complement.

A

C

B

Since m∠A = 22º is given, we know m∠B = 68º since there are 180º in the triangle. Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A.

If we write, m∠B = 90º - m∠A    (or m∠A = 90º - m∠B ), and we substitute into the original observation, we have:

A 2-column table with 5 rows. Column 1 is labeled Days to Set Up with entries 1.5, 3, 4.5, x, 7.5. Column 2 is labeled Number of
Lorico [155]

This directly proportional relationship between p and q is written as p∝q  where that middle sign is the sign of proportionality. The value of x is 6.

<h3>What are directly proportional and inversely proportional relationships?</h3>

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

 p = kq

where k is some constant number called the constant of proportionality.

This directly proportional relationship between p and q is written as

 p ∝ q  where that middle sign is the sign of proportionality.

In a directly proportional relationship, increasing one variable will increase another.

Now let m and n be two variables.

Then m and n are said to be inversely proportional to each other if

m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}

(both are equal)

where c is a constant number called the constant of proportionality.

This inversely proportional relationship is denoted by

m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}

As visible, increasing one variable will decrease the other variable if both are inversely proportional.

Let the days to set up with entries be represented by a, while the number of concerts is represented by b. Now, It is known that the days to set up with entries and the number of the concert are in a relationship. Therefore, we can write the relationship as,

a ∝ b

a = k b

Now, if we substitute the values from the first row, we will get,

1.5 = k × 1

1.5 = k

Thus, the value of k is 1.5.

Now, if we substitute the entries from the 4th row, we will get,

a = k × b

x = 1.5 × 4

x = 6

Hence, the value of x is 6.

Negative X +3+ 3X equals 23
Nadusha1986 [10]

Answer:

X = 10

Step-by-step explanation:

First you subtract -X from 3x to get 2x +3 =23

then you subtract 3 from both sides to get 2x = 20

then finally, you divide both sides by two to get x = 10

And if you plug 10 back in you get -10 + 3 + 30 = 23

-10 + 3 = -7

-7 + 30=23

23=23
