What is the length of the altitude of an equilateral triangle whose side has a length of 8?

1 answer:

4 0

Using Pythagorean theory the square of the hypotenuse minus the square of the base equals the square of the other side (altitude).

So 8*8=64, 4*4=16, 64–16=48 so the altitude of the triangle is the √48.

Answer:

k = 45*

2k = 90*

Step-by-step explanation:

K will be the same as the 45* degrees, as it is across from it.

2k is twice k, which is 90*.

45* + 45* + 90* = 180*

Nataliya [291]

Answer:

28.5^2

Step-by-step explanation:

The formula is, b(base)+c(height)= b+c over 2. b+c/2.

B=19ft in this problem.

C=38ft

Knowing this, we can further simplify.

19+38/2

Now, we add 19 and 38.

(57)

57/2= 28.5

So, the anwser is 28.5^2
