The fraction he added is 6/30, or 1/5.
I'm not 100% sure about the equation you want me to use but I did the work this way:

5/6+x/30=31/30 (the denominator has to equal 30 because you are adding. You need a common denominator which is why you need to change 5/6. We can label the numerator as a hidden value x)

25/30+x=31/30

You can then work backwards and basically subtract 25 from 31 and get 6; so x=6

I only need help on questions 6 and 7. (Use the congruent figure on top to answer 6 and 7.)
allsm [11]

Answer:

See below.

Step-by-step explanation:

All statements of congruent angles and congruent segments are correct.

A similarity statement can be written ...

Write a similarity statement ...

ABCD ~ HJKL

The reason written in the problem is incorrect. The polygons are similar, not congruent, so you cannot state that they are congruent as a reason for them to be similar.

This is the correct reason:

"The reason as why the two shapes are similar is that each angle A, B, C, D is congruent to each corresponding angle H, J, K, L, respectively, and the lengths of corresponding sides are proportional."

"A similarity ratio is a ratio that compares the <u>lengths</u> of the corresponding sides of two similar polygons. The ratio is written in the same order as the <u>two</u>

<u>polygons.</u>"

For the similarity ratio, we use two corresponding sides.

AB = 8; HJ = 12

AB/HJ = 8/12 = 2/3

The similarity ratio of ABCD to HJKL is 2/3.
