The top of a 230 foot vertical tower is to be anchored by cables that make an angle with a measure of 50 degrees with the ground
Triss [41]

9514 1404 393

Answer:

  • cable length: 300.2 ft
  • anchor distance: 193.0 ft

Step-by-step explanation:

The side given is opposite the given angle. We want to find both the hypotenuse and the adjacent side in the right triangle that models the geometry.

  Sin = Opposite/Hypotenuse

  sin(50°) = (230 ft)/h

  h = (230 ft)/sin(50°) ≈ 300.24 ft

The length of the cable must be about 300.2 feet.

__

  Tan = Opposite/Adjacent

  tan(50°) = (230 ft)/d

  d = (230 ft)/tan(50°) ≈ 192.99 ft

The cable must be anchored about 193.0 ft from the tower.

What is 1/4 as a whole number?
wlad13 [49]

The whole number of \dfrac{1}{4} is \boxed{0.25}.

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The number is \dfrac{1}{4}.

Explanation:

The whole numbers is the series of numbers that starts from zero.

The natural numbers are those numbers that start from one.

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The given number is \dfrac{1}{4}.

Consider the number \dfrac{1}{4} as \text{A}.

A = \dfrac{1}{4}

Divide 1 by 4 to obtain the whole of \dfrac{1}{4}.

\begin{aligned}\text{A}&= \frac{1}{4}\\&= 0.25\\\end{aligned}

The decimal expansion of \dfrac{1}{4} is 0.25.

The whole number of \dfrac{1}{4} is \boxed{0.25}.
