How do I do this? It is a regular hexagon with a height of 30. We have to find the perimeter of it.

Perimeter = 60√3

Step-by-step explanation:

I can't see any other way of doing this than by using trig.

Draw IS which is also 30.

Now we use that midpoint. Cos(30) = 15/IL

Cos(30) = √3/2 = adjacent / hypotenuse

The adjacent side = 15

15/(√3/2) = hypotenuse

Hypotenuse = 15*2 √3 / 3 = 10 √3

The hypotenuse is IL which is one of the sides.

The perimeter = 6*IL = 6 * 10 √3 = 60√3

Your answer is very close to mine. I'd sure like to know how you did it.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
