A regular pentagon ABCDE is shown Work out the size of X

nikdorinn [45]

The sum of the angles in a pentagon is 540°.

This means that each angle is 108°.

Inside you pentagon, a triangle is drawn. This triangle is isosceles, because the corners are on the points of the regular pentagon. You know that angle C is 108°.

Angles in a triangle add up to 180°.

B and D will be the same size as this is isosceles.

180°-108° = 72°

This is B and D. You only need one of these, so you divide by 2.

The answer is 36°.

Hope this helps :)

What is 1000 k = to but it has to be a gram .any get it cause I don't help me

denpristay [2]

You need to convert 1000kg to grams? There are 1000g $\frac{1000g}{kg}$
Now what you need to do is multiply the number of kg you have by your conversion fractions, making sure that grams is on top so you end up with grams in your answer: $\frac{1000kg}{g}$ * $\frac{1000g}{kg}$

Kg cancel, and you are left with 1,000,000g
This means that there are 1,000,000g in 1000kg
Hope this helps!
