Mathematics

Answer:

Height ( h) = 12 units.

Step-by-step explanation:

Given  : An equilateral triangle with side = 8 √3.

To find : What us the length of the altitude of the equilateral triangle .

Solution : We have given equilateral triangle with side = 8 √3.

By taking the half triangle,

By the Pythagorean theorem :

(Hypotenuse)² = ( adjacent)² + (opposite)².

Plug the values Hypotenuse = 8√3 , adjacent = 4√3 , opposite = h.

(8√3)² = ( 4√3)² + (h)².

192 = 48 +  (h)².

On subtracting by 48 both sides.

192 -48 =  (h)².

144 =  (h)².

On taking square root .

h = 12 .

Therefore, Height ( h) = 12 units.

Three times a number increased by ten is equal to twenty
JulijaS [17]

Answer:

The number is 10/3

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

Three times a number increased by ten is equal to twenty

(3n) + 10 = 20

<u>Step 2:  Subtract 10 from both sides</u>

3n + 10 - 10 = 20 - 10

3n = 10

<u>Step 3:  Divide both sides by 3</u>

3n / 3 = 10 / 3

n = 10/3

Answer:  The number is 10/3
