Answer:

Option A is correct that is Required additional information is ∠BDC and ∠AED are right angles.

Step-by-step explanation:

We need to find an additional information used to to prove ΔCEA ~ ΔCDB

In ΔCEA and  ΔCDB

    ∠ACE = ∠BCD  ( common angle in both triangle )

if,  ∠AEC = ∠BDC  ( both are right angles )

then ΔCEA ~ ΔCDB by AA similarity criteria.

Therefore, Option A is correct that is Required additional information is ∠BDC and ∠AED are right angles.

Which of the sequences is an arithmetic sequence?
Bogdan [553]
<h3>Answer: Choice A</h3>

This is because we're adding -6 to each term, i.e. subtracting 6 from each term, to get the next term

  • -2+(-6) = -8
  • -8+(-6) = -14
  • -14+(-6) = -20
  • -20+(-6) = -26

and so on. The gap between adjacent terms is the same width. We say that the common difference is d = -6.

Is f(x)=3/4 a function?
Marat540 [252]

Answer:

Yes, f(x) = \frac{3}{4} is a constant function.

Step-by-step explanation:

A function is defined to be a relation from 1 set of numbers to another set of numbers.

The main condition for a relation to be a function is that for every number in the domain there should be a <u>unique image</u>

Here the given function is f(x) = \frac{3}{4}

This function is a constant function and gives the value 0.75 for all values of x.

Hence the graph would be a straight line parallel to the x-axis passing through y = 0.75.

Hence the f(x) = 0.75 is a function.

I really dont understand this question, help? i dont need steps or anything
Agata [3.3K]

Answer:

Step-by-step explanation:

135 degrees is an exterior angle. meaning the interior angle is 45. meaning x is 45 because of the isosceles triangle theorem that states if two sides are equal on a triangle then their angles opposite those are congruent. a triangle measures up to 180 in general. so 45 plus 45 is 90. 180 minus 90 is 90. so angle x is 45 and angle y is 90
