Answer:

∠TRS = 40°

Step-by-step explanation:

∠UTS is an exterior angle of the triangle

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, that is

∠UTS = ∠TRS + ∠RST

9x - 15 = 3x + 16 + x + 9

9x - 15 = 4x + 25 ( subtract 4x from both sides )

5x - 15 = 25 ( add 15 to both sides )

5x = 40 ( divide both sides by 5 )

x = 8

∠TRS = 3x + 16 = (3 × 8) + 16 = 24 + 16 = 40°

Elden [556K]

Answer:

the number of feet in the case when the person rode around the ferris wheel is 2,700 feet

Step-by-step explanation:

The number of feet in the case when the person rode around the ferris wheel is shown below:

Given that

There is 450 feet across the center

And, it is 6 times rounded

So, the number of feet is

= 450 × 6

= 2,700 feet

Hence, the number of feet in the case when the person rode around the ferris wheel is 2,700 feet

What is 18x-9(x-1)=5(3x+3)

Alexandra [31]

Answer:

-4

Step-by-step explanation:

18x - 9(x - 1) = 5(3x + 3)

Step 1: Distribute

18x - 9x - 9 = 15x + 15

Step 2: Combine like terms

9x - 9 = 15x + 15

Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side

9x - 9 = 15x + 15

-9x -9x

-9 = 6x + 15

-15 -15

-24 = 6x

/6 /6

-4 = x

The tile along the edge of a triangular community pool needs to be replaced. Which expression represents the total perimeter of

topjm [15]

The total perimeter of the pool edge $\boxed{12{x^2} + 15}$ .Option A is correct.

Further Explanation:

The formula of area of square can be expressed as follows,

${\text{Area}} = \dfrac{1}{2} \times \left( b \right) \times \left( h \right)$

The formula of perimeter of the triangle can be expressed as follows,

$\boxed{{\text{Perimeter}} = 3 \times s}$

Here, s represents the side of square.

Given:

The options are as follows,

A. ${12x^2} + 15$

B. ${20x^2} + 25$

C. ${12x^2} + 8x +25$

D. ${24x^2} + 16x + 50$

Explanation:

Option A is ${12x^2} + 15.$

12 and 15 are the multiple of 3.

$\begin{aligned}{\text{Perimeter}} &= 12{x^2} + 15\\&= 3\left( {4{x^2} + 5} \right)\\\end{aligned}$

Therefore, the perimeter of the pool is ${12x^2} + 15.$

The total perimeter of the pool edge $\boxed{12{x^2} + 15}$ .Option A is correct.

Option A is correct.

Option B is not correct.

Option C is not correct.

Option D is not correct.
