Step-by-step explanation:

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.

So, a traingle is 180 degrees.

A line is also 180 degrees.

We know that the angles that make up the triangle are 46, 90, and a missing angle

We need to find the missing angle to find x

To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.

So:

180-90

=

90

90-46

=

44

So we know the missing angle is 44 degrees.

Let subtract the missing angle(44 degrees) by the 180 degrees of the line:

180-44

=

136

THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER

So x equals 136. This is the missing angle x.

So, remember, both the line and the traingle are 180 degrees.

They both need to find the missing value, which we know is 44

The rest of both the triangle and line is 136 degrees.

Well, 136 degrees on the triangle is the known 90+46 degrees.

Since this will be the same on the line, we can think of x as:

90+46

This looks like answer 1.

Hope this helps! :)

A)5
B)7

PS: por favor explicar a resposta

Answers

Answer:

15

Step-by-step explanation:

1) we can use a proportion

2.25 : 33.75 = 1 : x

in a proportion the product of the terms nearest to equal is equal to the therms furthest than equal

33.75 * 1 = 2.25 * x

x = 33.75/2.25 = 15

Skyler leased a car for 36 months. Her contract said she can drive 5,000 miles per year
and will have to pay $0.30 per mile above the allowance. If she turns in the car after her
lease term with 25,000 miles driven, how much will Skyler have to pay for the extra
miles (if any)?

Answers

Answer:

She has to pay an extra $3,000

Step-by-step explanation:

36 months is 3 years. She is allowed 5,000 miles per year, so 3 x 5,000 = 15,000 miles allowed. But she drove 25,000.

25,000 - 15,000 = 10,000 extra miles

10,000 x 0.30 cents/mile = 3,000

Skyler have to pay for 10000 miles the amount is $3000.

What is the equation?

A equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Skyler leased a car for 36 months.

Her contract said she can drive 5,000 miles per year and will have to pay $0.30 per mile above the allowance.

If she turns in the car after her lease term with 25,000 miles driven.

There are 12 months in a years so in 36 months,

[tex]=\dfrac{36}{12}\\\\=3 \ \rm years[/tex]

There are 3 years in 36 months.

Her contract said she can drive 5,000 miles per year, so in 3 years he drives the car;

[tex]\rm = 5000\times 3\\\\=15000 \ miles[/tex]

If she turns in the car after her lease term with 25,000 miles driven, how much will Skyler have to pay for the extra miles is;

= 25000 - 15000

= 10000

He has to pay extra amount for 10,000 miles which is;

[tex]= 10000\times 0.30\\\\= 3000[/tex]

Hence, Skyler have to pay for 10000 miles the amount is $3000.

[tex]\sqrt{\frac{y-1}{2} }[/tex] = (x - 3)² ( take the square root of both sides )

Solve the following system of equations using substitution.

4x + 2y = 12
x = y + 3

Answers

Answer:

x = 3

y = 0

Step-by-step explanation:

The method of substitution is when one solves an equation for one of the variables, and then substitutes the expression into the other equation. After doing so, one will solve the other equation for the remaining variable and then backsolve for the first variable.

4x + 2y = 12

x = y + 3

The second equation is already sovled for parameter (x), subttiute this into the other equation,

4(y + 3) + 2y = 12

Distribute,

4y + 12 + 2y = 12

Simplify,

6y + 12 = 12

Inverse operations,

6y + 12 = 12

-12

6y = 0

/6

y = 0

Backsolve for (x), substitute the value of (y) into the equation for (x) and solve,

x = y + 3

x = 0 + 3

x = 3

Answer: look at the picture, sorry I can’t solve x = y + 3 for x.

What is the measure of the smallest angle?

54

Answers

Answer:

smallest   angle measure 39 degrees

Step-by-step explanation:

the sum of the three interior angles in a triangle is always 180°

x= smallest

x +x+24 + 2x = 180

4x +24 = 180

4x = 156

x = 39

Answer:

B. 39°

Step-by-step explanation:

x + 24 + 2x + x = 180 is the equation I'll use.

x + 24 + 2x + x = 180 {Step 1: Combine 2x, x, x to get 4x.}

4x + 24 = 180 {Step 2: Subtract 24 from both sides (180 - 24 = 156)}

4x = 180 - 24

4x = 156 {Step 3: Divide both sides by 4 (156 / 4 = 39)}

x = 156/4

x = 39

The smallest angle is 39°. (The other two angles are 63° and 78°, respectively.)
