Un jardín rectangular de 50 cm de largo por 34 m de ancho está rodeado por un camino de arena uniforme.Halla la anchura de dicho

Anastasy [175]

Answer:

5.85 m

Step-by-step explanation:

The width of the sand road can be calculated knowing its area and the dimensions of the rectangular garden as follows:

$A_{g} = a.b$

Where:

Ag: is the area of the rectangular garden

a: is the length of the rectangular garden = 50 cm = 0.5 m

b: is the width of the rectangular garden = 34 m

$A_{s} = 540 m^{2}$

Where:

As: is the area of the sand road

The relation between the area of the sand road and the area of the rectangular garden is the following:

$A_{s} + A_{g} = (a+2x)*(b+2x)$

$540 m^{2} + 0.5m*34m = ab + 2ax + 2bx + 4x^{2}$

$557 m^{2} = ab + 2x(a + b) + 4x^{2}$

$557 m^{2} - 17m^{2} - 2x(34.5 m) - 4x^{2} = 0$

$540 - 69x - 4x^{2} = 0$

By solving the above equation for x we have two solutions:

x₁ = -23.10 m

x₂ = 5.85 m

Taking the positive value, we have that the width of the sand road is 5.85 m.

I hope it helps you!

Arc QVT measures 156

mixas84 [53]

Answer:

Angles QRT and QST both measure 78 degrees

Step-by-step explanation:

We are given that

Measure of arc QVT= $156^{\circ}$

We know that

Central angle is equal to measure of intercepted arc

$arc QVT=\angle QPT=156^{\circ}$

Inscribed angle formed by same arc are equal

$\angle QRT=\angle QST$

Inscribed angle is equal to half of the central angle.

$\angle QRT=\angle QST=\frac{1}{2}\times 156=78^{\circ}$

Hence, measures of angle QRT and angle QST are equal.

Therefore, option A is true.
