Question

use the 30-60-90 triangle relationship below to find the length of the altitude you drew in part 1 leave your answer in simplest form

Answer 1

this is the triangle in part 1

Answer 2

would i then plug in 8 for all the S or would it be 4

Answer 3

so my answer would be 4*√3=6.9

Answer 4

So it is to the most simplest radical form right?

Answer 5

Now the next question asks me to use the height i found to find the area of the triangle and round the the nearest 10th

i would do
1/2 (b*h)
1/2 (4*6.9)
area = 13.8 but round to the nearest to the nearest 10th would be

Answer 6

13.8 still

Answer 7

it tells me to find the area of the equilateral triangle

Answer 8

wouldnt you do 1/2 (base * height) to find the area

Answer 9

and not add sqrt(3)
