Answer:

n = 3.17

Step-by-step explanation:

Given:

8n − 6 = 2n + 13

Collect like terms

8n - 2n = 13 + 6

6n = 19

Divide both sides by 6

n = 19/6

= 3.167

Approximately to the nearest tenth

n = 3.17

On a sunny day, a flag pole and its shadow form the sides of a right triangle. if the hypotenuse is 35 meters long and the shado

Triss [41]

We can use Pythagorean's Theorem in order to find the remaining side length
a^2+b^2=c^2
Let a be the shadow length
Let b be the height of the flagpole
Let c be the hypotenuse
28^2+b^2=35^2
784+b^2=1225
b^2=1225-784
b^2=441
b=√441
b=21
Therefore the flagpole is 21 meters tall.
Hope this helps!
