1.What is the length of the altitude of an equilateral triangle with side lengths of 34 inches?
sweet [91]

Answer:

Step-by-step explanation:

Remark

<u>Question One</u>

It's equilateral. All three sides are equal. The base is 34 as well. So two right angles can be formed on the base by dropping the altitude from the top vertex.

Givens

altitude = h

a = 34/2 = 17

hypotenuse = 34

Formula

a^2 + h^2 = c^2

Solution

17^2 + h^2 = 34^2

289 + h^2 = 1156

h^2 +289 =1156

h^2 = 1156 - 289

h^2 = 867

sqrt(h^2) = sqrt(867)

h = 29.444

==============

<u>Question Two</u>

Givens

b = 10 feet

c = ?

height = h = 16

Formula

c^2 = b^2 + h^2

Solution

c^2 = 10^2 + 16^2

c^2 = 100 + 256

c^2 = 356

sqrt(c^2) = sqrt(356)

c = 18.87

Help i don't get it. I've been trying
ASHA 777 [7]

Answer:

JK = 42 , KL = 78

Step-by-step explanation:

JK + KL = JL , substitute values

4x + 6 + 7x + 15 = 129 , that is

11x + 21 = 120 ( subtract 21 from both sides )

11x = 99 ( divide both sides by 11 )

x = 9

Then

JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42

KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78
