Question

use 1.7 as the value of the square root of 3 what is the are of the equilateral tirangle with a side of 10yds

Answer 1

The altitude of the triangle is 5 times the square root of 3, or 5 times 1.7.
Area of a triangle = 1/2 bh, so Area = 1/2 times (10) times (5 times 1.7) = 42.5 or more accurately 43.30127019 using the correct value of the square root of 3.

Answer 2

16) If one part is 12, then the different part is 12, so both lengthy aspects jointly are 24. That leaves 10 for the different 2 aspects, so one short part is 5. the section is 12x5 = 60 17) 2 radii would properly be drawn from opposite corners of the sq. to sort a diagonal of length 12. The 6?2 that you calculated is the dimensions of the fringe of the sq.. Squaring this yields seventy 2, the section. 18) For a circle A = pi(r^2) so 16pi = (4^2)pi and radius = 4 If radius = 4 diameter = 8 and circumfrence = 8pi 19) If diameter = 12 then radius = 6 and section = (6^2)pi = 36pi 20) you're desirable. If the perimiter is 12, then both part is 4, and 0.5 the bottom = 2. next verify the height. employing a^2 + b^2 = c^2, and fixing for a, you get a^2 = c^2 - b^2, then a^2 = 4^2 -2^2 = 12. So, a = 2?3, ensuing in A = 2(2?3) = 4?3 SEE! you're smarter than you imagine!

Answer 3

The area of a triangle can also be found by multiplying two of the sides together, multiplying by the sine of the angle between them, then dividing by 2. (If you don't divide by 2, you get the area of a parallelogram. If it's a parellogram made up of right angles, the sine of 90 degrees is 1, giving you the formula for area of a rectangle).

Since you're talking about an equilateral triangle, you know the angle between the sides is 60 degrees.

In this case, you get (10*10*sine(60))/2 =(100*.866)/2 = 86.6/2 = 43.3.

Since you're using the square root of 3, you're probably supposed to use Heron's formula, though.

Answer 4

50 Square yards

Answer 5

wildly, I'm guessing (s/2)²√3. Oh maybe because I answered this twice already.

Answer 6

42.5 yd^2

Answer 7

42.5yds
