Answer 1

Answer:

x = 71°

Option B is correct answer.

Step-by-step explanation:

We need to find for what value of x is [tex]sin\: x = cos 19^{\circ}[/tex], where 0°< x < 90°?

Solving:

[tex]sin\: x = cos\: 19^{\circ}\\Finding \:cos\: 19^{\circ}=0.94551\\Putting\:value:\\sin\:x=0.94551\\Now\:taking\:sin\:inverse\\x=sin^{-1}(0.94551)\\x=71^{\circ}[/tex]

So, we get x = 71°

Option B is correct answer.

Absolute value is basically:

A. A number's distance from 0 on a number line

B. The greatest number on a number line

Answers

Answer:

A because absolute value doesn't change the actual value of the number, just makes it positive no matter what, but it's still the same distance from 0, just in the opposite direction.

Step-by-step explanation:

Answer:

A : a number distance form 0n the number line

Step-by-step explanation:

ex: if you want to find the absolute value of -4 you would look at the distance from zero so it would be 4 from zero so the absolute of -4 is 4

HELP ME PLEASEEEEEEEEEEEE

Answers

Answer:

m<1 = 54

m<3 = 54

m<4 = 126

Step-by-step explanation:

<1: <2 and <1 are supplementary angles.

<3: <2 and <3 are supplementary angles. <1 and <3 are vertical angles.

<4: <2 and <4 are vertical angles.

Supplementary angles equal to 180 degrees.

Vertical angles are equivalent.

Let's solve for <1.

<2 + <1 = 180 --> Due to supplementary angles

126 + <1 = 180 --> Substitution

126 + <1 - 126 = 180 - 126 --> Subtracted 126 on both sides

<1 = 54 --> Simplified

Let's solve for <3.

<3 = <1 --> Due to vertical angles

<3 = 54 --> Substitution

Let's solve for <4.

<4 = <2 --> Due to vertical angles

<4 = 126 --> Substitution

Therefore, m<1 = 54, m<3 = 54, and m<4 = 126

Hope this helped! <3

1 is 54 degrees

Answer:

Steps: 1) Isolate the absolute value on the LEFT Side of the equation ... 12) A recent poll suggests that 47% of American citizens are going to vote for the ... margin of error of £4.5%. Set up and solve an absolute value inequality to determine the range of possible ... determine if the Democratic candidate will win the election?

Step-by-step explanation:

The percentages candidate could earn falls in the range of absolute value inequality |47 - x| ≤ 4.5.

What is Absolute Value Inequality?

Absolute value inequalities are kind of inequality expressions which includes the absolute value symbol in the expression.

For example : |x - 5| < 4 is an absolute value inequality.

Given that,

Percentage of American citizens going to vote for candidate B = 47%

Tolerance level = 4.5%

Suppose x be the percent of voters who will vote for candidate B.

Value of x can be,

47% + 4.5% = 51.5%

Or,

47% - 4.5% = 42.5%

The absolute value inequality for the situation is,

|47 - x| ≤ 4.5

Hence the absolute value inequality is |47 - x| ≤ 4.5.

The length of a rectangle is 5 less than 3 times the width. What is the length?

Perimeter = 46 inches
Write an inequality or equation, then solve.

Answers

Answer:

Let the width of the Rectangle be x inches

Then, length is (3x-5) inches

Perimeter of the Rectangle= 46 inches (given)

According to the above problem,

Equation :---- Perimeter=2(length+breadth)

2{(3x-5)+x}=46

2(4x-5)=46

(4x-5)=46/2=23

4x=(23+5)=28

x=28/4

x=7

So, length of the Rectangle is {(3×7)-5}=16 inches

and width is= 7 inches

Answer:

So, length of the Rectangle is {(3×7)-5}=16 inches
