A triangle has side lengths of (5h – 4k) centimeters, (10h + 7m) centimeters, and
larisa [96]

A mathematical expression which best represents the perimeter of this triangle is (15h - 6k + 12m) centimeters.

<u>Given the following data:</u>

Length A = (5h – 4k) centimeters

Length B = (10h + 7m) centimeters

Length C = (5m – 2k) centimeters.

<h3>What is a triangle?</h3>

A triangle can be defined as a two-dimensional shape that comprises three (3) sides, three (3) vertices and three (3) angles.

<h3>How to calculate the perimeter of a triangle.</h3>

Mathematically, the perimeter of a triangle is given by this formula:

P=A+B+C

<u>Where:</u>

  • A, B, and C are length of sides.

Substituting the given parameters into the formula, we have;

P=(5h - 4k) +(10h + 7m) +(5m - 2k)\\\\P=5h+10h-4k-2k+7m+5m\\\\P=(15h-6k+12m)\;centimeters

if you see this I really need help on this question asap ty so much... "The flagpole in the diagram below has a height of 10ft.
aev [14]

Answer:

15.62 feet

Step-by-step explanation:

If the flagpole is 10ft tall and the shadow is 12ft long, and you need to find the distance from the top of the flagpole to the far end of the shadow, to get your answer, you must use the pythagorean theorum.

a^{2} + b^{2} = c^{2}

let height of flagpole = a

let length of shadow = b

let distance between the two = c

10^{2} + 12^{2} = c^{2} \\100 + 144 = c^{2}\\244 = c^{2}\\\sqrt{244} = \sqrt{c^{2}} \\\sqrt{244} = c\\15.62 = c
