9. (04.01 LC) The vertices of a quadrilateral ABCD are A(4,8), B(10, 10), C(10,4), a true about the quadrilaterals? (5 points) A- the measure of their corresponding angles is equal B the ratio of their corresponding angles is 1:2 C the ratio of their corresponding sides is 1:2 D the size of the quadrilaterals is different but shape is same​

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

the answer to this is a. a^2 + b^2 = c^2

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
