Answer:

I would probably guess B.

Step-by-step explanation:

because the first row is x + 2 = y,

the second row is x + 3 = y,

the third is x + 4 = y,

the fourth is x + 6 = y,

so there is no pattern, therefore is is not D.

For A, the ratios are equal, but this is not the case for 4/7, so it can't be A.

C doesn't make sense, because some pairs are simplified, like the first two, but the last two are not.

So, you can make your own choice.

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 :)
