A guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.

frutty [35]

Answer:

The length of the wire is 76.19 m.

Step-by-step explanation:

It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.

It means base of the right angled triangle is 40 m.

The wire makes an angle of 58deg 20min with the ground.

1 degree = 60 min

Using this conversion convert the given angle in degree.

$58^{\circ}20'=58^{\circ}\frac{20}{60}^{\circ}=58\frac{1}{3}^{\circ}=\frac{175}{3}^{\circ}$

In a right angled triangle

$\cos \theta=\frac{adjacent}{hypotenuse}$

$\cos (\frac{175}{3}^{\circ})=\frac{40}{hypotenuse}$

$0.525=\frac{40}{hypotenuse}$

$hypotenuse=\frac{40}{0.525}$

$hypotenuse=76.190$

Therefore the length of the wire is 76.19 m.

Hi there! Three days ago I ordered 8 Neat cupcakes. This week I'd like 50% fewer than that.

Furkat [3]

Total cup cake ordered = 8

Percentage 'P' of a quantity x can be calculated using:

p/100 * x

Here,

P = 50%

x = 8

Put these values in formula.

50/100 * 8

=> 1/2 * 8

=> 4

So, the 50% fewer cupcakes would be (8 - 4) = 4 cupcakes.

Answer:

27. Natural number

29. Rational number

31. Rational number

43.

$\frac{ - 60}{11} < - 3 < \sqrt{11} < 5.5 < \sqrt{31}$

45.

$\sqrt{7} < \sqrt{8} < 2.9 < 3 < \frac{10}{3}$
