Answer:

Part 1) x=44.80\ units

Part 2) y=56.85\ units

Step-by-step explanation:

Part 1) Find the value of x

we know that

In the right triangle of the figure

The tangent of angle of 52 degrees is equal to divide the opposite side to the angle of 52 degrees (x units) by the adjacent side to the angle of 52 degrees (35 units)

tan(52\°)=x/35

Solve for x

x=(35)tan(52\°)

x=44.80\ units

Part 2) Find the value of y

we know that

In the right triangle of the figure

The cosine of angle of 52 degrees is equal to divide the adjacent side to the angle of 52 degrees (35 units) by the hypotenuse (y units)

cos(52\°)=35/y

Solve for y

y=35/cos(52\°)

y=56.85\ units

Answer:

x = 56.85 units and y = 44.80 units.

Step-by-step explanation:

From the given figure it is clear that the given triangle is a right angle triangle.

According to the angle sum property of triangle the sum of interior angle of a triangle is 180°.

z^{\circ}+90^{\circ}+52^{\circ}=180^{\circ}

z^{\circ}+142^{\circ}=180^{\circ}

z^{\circ}=180^{\circ}-142^{\circ}

z^{\circ}=38^{\circ}

Law of Sine:

\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}

Using Law of Sine we get

\dfrac{x}{\sin 52^{\circ}}=\dfrac{y}{\sin 90^{\circ}}=\dfrac{35}{\sin 38^{\circ}}

\dfrac{x}{\sin 52^{\circ}}=\dfrac{35}{\sin 38^{\circ}}

x=\dfrac{35}{\sin 38^{\circ}}\times \sin 52^{\circ}

x\approx 44.80

The value of x is 44.80 units.

\dfrac{y}{\sin 90^{\circ}}=\dfrac{35}{\sin 38^{\circ}}

y=\dfrac{35}{\sin 38^{\circ}}\times \sin 90^{\circ}

y\approx 56.85

Therefore, the value of y is 56.85 units.

A person jogged 10 times along the perimeter of a rectangular field at the rate of 12 kilometers per hour for 30 minutes. If fie
balu736 [363]

Answer:

20,000m²

Step-by-step explanation:

If they jog 12 km/h for half an hour, they have covered.

12 X 0.5 = 6km in 10 circuits. Making 1 perimeter

6 / 10 =0.6 km (600 m).

To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.

So L = 2W

Perimeter = 2W + 2L

600 m = 2W + 2(2W)

600 m = 6W

W = 100 m

L = 200 m

Area = 100 X 200 = 20,000 m²
