Answer:

x=115 y=65

Step-by-step explanation:

You get 115 for X because angle x is vertical to 115 degrees.

You get 65 because y is supplementary to x, and 180-65=115.

Solve for x using figure to the right. Pls answer this it is urgent
goldenfox [79]

Answer:

Therefore the value of x = 10 units

Step-by-step explanation:

Let label the Triangles first,

Δ ABC a right triangle at ∠ A =90°

Δ ADB andΔ ADC a right triangle at ∠ D =90°

Such that

AD = x

BD = 50

CD = 2

∴ BC = BD + DC = 50 + 2 = 52

To Find:

x = ?

Solution:

In right triangle  By Pythagoras Theorem,

(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}

In right triangle Δ ADB andΔ ADC  By Pythagoras Theorem we will have,

AB² =  BD² + AD²

AB² = 50² + x²            ..................equation ( 1 )

and

AC² = DC² + AD²

AC² = 2² + x²             ...................equation ( 2 )

Now in right triangle Δ ABC,

BC² = AB² + AC²

Equating equation  (1 ) and ( 2 ) and the given value we get

52² = 50² + x² + 2² + x²

∴ 2x² = 2704 - 2504

∴ 2x² =200

∴ x^{2} =\frac{200}{2}\\\\\therefore x=\pm\sqrt{100} \\\\ \textrm{x cannot be negative}\\\therefore x= 10\ unit

Therefore the value of x = 10 units

Your family is installing a new square pool in the backyard. The existing patio has a side length of 8 feet. How much of the pat
trasher [3.6K]

The question is an illustration of perimeters.

The amount of patio to remove to install the pool is 8 feet.

From the question, we have:

\mathbf{Length\ of\ the\ pool = 8}

\mathbf{Length\ of\ walkway = 1}

The perimeter of the patio is:

\mathbf{P_p = 4 \times Length\ of\ the\ pool}

\mathbf{P_p = 4 \times 8}

\mathbf{P_p = 32}

A 1ft walkway means that;

1ft would be subtracted from both sides of the patio before installing the pool

So, the perimeter of the patio in terms of the length of the pool is:

\mathbf{P_p = 4 \times (x  +2)}

Equate both expressions

\mathbf{P_p = P_p}

\mathbf{4 \times (x  +2) = 32}

Divide both sides by 4

\mathbf{x  +2 = 8}

Subtract 2 from both sides

\mathbf{x = 6}

So, the perimeter of the pool is:

\mathbf{P_{pool} = 4 \times 6}

\mathbf{P_{pool} = 24}

The amount of patio to remove is:

\mathbf{Amount = P_p - P_{pool}}

So, we have:

\mathbf{Amount = 32 - 24}

\mathbf{Amount = 8}

Hence, 8ft of the patio would be removed to install the pool
