Answer:

x=18

Step-by-step explanation:

Hey There!

So if you did not know all of the angles in a triangle will add up to equal 180

So we use the equation

180=2x+3x+5x

and solve for x

step 1 combine like terms

2x+3x=5x

5x+5x=10x

so now we have

180=10x

step 2 divide each side by 10

180/10=18

therefore x = 18

Answer:

y =2

x=6

Step-by-step explanation:

We can use ratios to solve

12        6

---- = -----

x           3

Using cross products

12*3 = 6x

Divide each side by 6

36/6 = 6x/6

6 =x

Do the same process for y

We can use ratios to solve

4        6

---- = -----

y           3

Using cross products

4*3 = 6y

Divide each side by 6

12/6 = 6y/6

2=y

Answer:

[tex]x < - 9[/tex]

Step-by-step explanation:

We can only find the range of the values of x by using triangle inequality,

[tex]x + 1 + x > 3x + 10 \\ \\ 1 - 10 > 3x - 2x \\ \\ - 9 > x[/tex]

Multiply through both sides by -1, we get,

[tex]x < - 9[/tex]

This means x = -10, -11, ... (which is not realistic because a side of a triangle cannot be a negative number)

Answer:

7/20

Step-by-step explanation:

Answer:7/10

Step-by-step explanation:

Here is the way that I think is the simplest method of changing a percentage a fraction. This percentage has two digits in it, so put it over a 1 and two zeros and then simplify. 35/100 is simplified to 7/20.

8.75 feet

Given that a 12 foot ladder leans against a building seven feet above the ground.

By using trigonometry ratio, the angle between the ladder and the ground will be

SinØ = opposite/ hypothenus

SinØ = 7 / 12

SinØ = 0.58333

Ø = Sin^-1(0.58333)

Ø = 35.69 degree

At what height would an 15 foot ladder touch the building if both ladders form the same angle with the ground?

Using the same trigonometric ratios

SinØ = opposite/hypothenus

Sin 35.69 = opposite/ 15

Cross multiply

Opposite = 15 × sin 35.69

Opposite = 8.75 feet

Therefore, the ladder will touch the building if both ladders form the same angle with the ground at height 8.75 feet.

The length of the diagonal is

, which is 111.80 yards.

The possible dimensions of the sports field are width 70 yards, length 7-3x yards.

Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction.

Given that, the width is at least 50 yards and area is (490-210x)

We can conclude the shape of the sports field is rectangular.

We need to find the Greatest Common factor between 490 and 210, this way:

490 = 2 × 5 × 7 × 7

210 = 2 × 5 × 3 × 7

Then the greatest common factor is 2 × 5 × 7 = 70

This GCF is also equal to 70 yards (given in option), therefore it's one of the dimensions of the sports field.

Now, we calculate the other side of the sports, this way:

Second dimension of the sports field = (490-210x)/70

= 7-3x

Hence, The possible dimensions of the sports field are width 70 yards, length 7-3x yards.

Answer:

If a quadrilateral has four congruent sides and four right angles, then it's a square (reverse of the square definition). If two consecutive sides of a rectangle are congruent, then it's a square (neither the reverse of the definition nor the converse of a property)

If you want to solve for h, then you could follow these steps.

9.80h+10 = 88.40

9.80h = 88.40-10 ... subtract 10 from both sides

9.80h = 78.40

h = 78.40/9.80 .... divide both sides by 9.80

h = 8

Valerie worked 8 hours on Friday.

As a check,

9.80h + 10 = 88.40

9.80*8 + 10 = 88.40

78.40 + 10 = 88.40

88.40 = 88.40

The answer is confirmed.

The graph of the linear function is represented by graph B.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

Given that the equation is 4x-2y=8, Convert the equation in slope-intercept form,

4x-2y=8

y = 2x - 4

Compare with the general form of the equation,

y = mx + c

y = 2x - 4

The slope is 2 and the y-intercept is -4 for the linear equation.

Therefore, the correct graph for the linear equation is B.

Answer:

a) 34.64 inches

b) The TV will not fit inside the TV cabinet

Step-by-step explanation:

Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )

a)If it is 20 inches tall, how wide is the screen ?

We solve using the formula:

Diagonal ² = Width² + Height²

Diagonal = 40 inches

Height = 20 inches

40² = Width² + 20²

Width² = 40² - 20²

Width = √40² - 20²

Width = √(1200)

Width = 34.641016151 inches

Approximately = 34.64 inches

b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?

From the above calculation, the width of the TV = 34.64 inches

Hence the width of the cabinet has to be equal to or more than 34.64 inches

Hence, The TV will not fit inside the TV cabinet
