An equilateral triangle has has an era of 43.5 square feet the height is 8.5 feet what is the Perimeter of the triangle
enot [183]

Answer:

30.7 ft

Step-by-step explanation:

<em>An equilateral triangle with area 43.5 has a height of 8.68 not 8.5</em>

<em>I will do the problem as written even though it is not a possible equilateral triangle</em>

<em>---------------------------------------------</em>

a = (1/2)bh

43.5 = (1/2)b(8.5)

43.5 = 4.25b

b = 43.5/4.25

b = 10.2352941176

-----------------------

p = 3b

p = 3 * 10.2352941176

p = 30.7058823528

~ 30.7 ft

MODELING WITH MATHEMATICS The fire escape forms a right triangle, as shown. Use the Pythagorean Theorem to approximate the dista
anastassius [24]

Answer:

x = 14.13ft

Step-by-step explanation:

Given

See attachment for illustration

Required

Find x

To do this, we apply Pythagoras theorem.

From the attachment, the length of the hypotenuse is 16.7ft

While the length of the opposite/adjacent is 8.9ft

Length x is calculated using:

16.7^2 = 8.9^2 + x^2

x^2 = 16.7^2 - 8.9^2

x^2 = 199.68

Take square roots

x = \sqrt{199.68

x = 14.13ft
